TL;DR
Every major AI language model — GPT-4, Claude, Gemini, LLaMA — was trained on text scraped from the internet without individual consent. Common Crawl, the foundation dataset behind most LLMs, has processed 3.1 billion web pages including blog posts, forum comments, Reddit threads, and personal websites. Your words, opinions, and personal stories are embedded permanently in AI model weights, and no privacy law — not GDPR, not CCPA, not COPPA — can technically remove them once training is complete.
What You Need To Know
- Common Crawl has archived 3.1 billion web pages (380TB) since 2008 — it is the foundation of GPT-3, GPT-4, LLaMA, Gemini, and nearly every major LLM trained in the past five years. If you posted anything on a publicly indexed website between 2008 and 2024, probability is high that your text is in there.
- The Pile (EleutherAI, 2020): 825GB of text from 22 curated sources — including Books3, which contains 196,640 copyrighted books scraped wholesale from Bibliotik, a piracy site, without compensation to a single author.
- LAION-5B: 5.85 billion image-text pairs scraped from the open web — includes medical images from academic hospital sites, personal photographs indexed by search engines, and content from private individuals who never consented to inclusion in any AI training corpus.
- Reddit sold API access to Google for $60 million per year (2024); Stack Overflow licensed its content to OpenAI — the users who created every question, answer, comment, and thread received nothing. The platforms captured all the value from a collective human knowledge project built over decades by volunteers.
- The Conversation Permanence Problem: GDPR and CCPA deletion requests are honored at the database level but cannot remove personal data embedded in trained neural network weights — regulators have accepted workarounds that do not technically satisfy the spirit of the law, and the personal data remains permanently encoded in billions of model parameters.
The Consent Vacuum: How AI Training Data Became a Legal Grey Zone
In the summer of 2020, when EleutherAI researchers assembled The Pile and pushed it to the internet as an open dataset for AI research, they did something that would have been legally unthinkable in any other industry: they packaged up 825 gigabytes of human expression — novels, blog posts, legal documents, academic papers, GitHub repositories, Reddit threads, and copyrighted books — and made it freely available for anyone to download and use to train neural networks. No one asked permission. No one sent consent forms. The data was simply collected, cleaned, and released.
This was not an aberration. It was, and remains, the standard practice of the entire AI industry.
The Consent Vacuum is the legal grey zone where AI training data collection happens without individual user consent, exploiting the gap between copyright law (which addresses works, not personal expression) and data protection law (which was written for databases, not neural networks). It is the space in which petabytes of human digital life were collected, aggregated, and processed into commercial AI systems worth hundreds of billions of dollars — while the individuals whose expression, creativity, and intellectual labor constituted that raw material received nothing and were asked for nothing.
Understanding the Consent Vacuum requires understanding what it is not. It is not primarily a copyright violation — though copyright violations certainly occurred. The majority of what is scraped from the internet is not copyrighted in any formal sense. A comment you left on a forum in 2011. A Yelp review you wrote in 2016. A Reddit post describing your experience with a medical condition. A tweet expressing your political opinion. A blog entry documenting your personal life. These are not works registered with the Copyright Office. They are not protected by the kind of formal intellectual property frameworks that would give you legal standing to file an infringement lawsuit.
But they are unambiguously personal data. Under the General Data Protection Regulation in the European Union, personal data means any information relating to an identified or identifiable natural person. Under the California Consumer Privacy Act, personal information includes any information that identifies, relates to, describes, or could reasonably be linked to a particular consumer. By those definitions, virtually everything a person posts online is personal data.
The problem is that data protection law was architected for databases. GDPR was designed to regulate companies that store your name in a customer record, your location in a GPS log, your purchase history in a transaction table. The law assumes that personal data exists as discrete, addressable records that can be identified, located, and deleted on request. That assumption holds for traditional databases. It does not hold for neural networks trained via gradient descent.
The Fair Use Fiction compounds this problem on the copyright side. The Fair Use Fiction is the invocation of copyright fair use doctrine to justify mass collection of personal data for commercial AI training — a legal argument that conflates copyright protection with data protection, treating the absence of copyright violations as permission for surveillance-scale data harvesting. AI companies have relied heavily on fair use arguments to defend their training data practices: the argument that training on copyrighted text is transformative, educational, or research-oriented in nature and therefore falls within the fair use exception to copyright law.
This argument faces a fundamental credibility problem. GPT-4 is a commercial product. The company that built it was valued at $157 billion in early 2024. The "research exception" in copyright fair use doctrine was not designed to cover commercial deployment of AI systems at planetary scale generating billions in revenue. Invoking research and education exceptions for a commercial product that charges monthly subscription fees requires a degree of legal creativity that courts are only now beginning to scrutinize.
The more important point, however, is that the Fair Use Fiction operates entirely in the wrong domain. Even if every AI training data collection practice were found to be copyright-compliant, that would tell us nothing about whether those same practices comply with data protection law. Copyright protects works. Data protection protects people. These are different legal frameworks governing different interests, and a ruling in one domain does not automatically resolve questions in the other.
The legal system is catching up — slowly, and with significant industry resistance. But for the billions of individuals whose personal expression was collected and embedded in AI model weights between 2008 and 2024, the legal remedies that eventually emerge will arrive too late to address the core problem: their data is already in there, and there is no technical mechanism to remove it.
Common Crawl: The Internet's Biggest Surveillance Operation Nobody Talks About
The Common Crawl Foundation is a San Francisco-based non-profit organization with a simple mission: crawl the web and make the data freely available. Founded in 2008, Common Crawl has spent the past sixteen years systematically archiving the publicly accessible internet. As of 2024, it has processed approximately 3.1 billion web pages and amassed roughly 380 terabytes of raw web data. It releases new crawls monthly.
Most people have never heard of Common Crawl. The AI companies that built their empires on its data have every incentive to keep it that way.
Common Crawl is the foundation of the modern AI industry. GPT-3, OpenAI's landmark 2020 language model, drew 57.5% of its training data directly from Common Crawl. GPT-4, which powers ChatGPT and is embedded in products used by hundreds of millions of people daily, was trained on Common Crawl data. LLaMA 1, 2, and 3 — Meta's open-source models — used Common Crawl as their primary text source. Google's Gemini family, the Falcon models from Technology Innovation Institute, Mistral's models, and virtually every other major LLM released in the past four years traces its linguistic intelligence back to Common Crawl's archive.
What is in that archive? Everything that was publicly accessible on the web and not actively blocked by robots.txt at the time of crawl. That includes personal blogs on WordPress and Blogspot dating back to 2008. Forum discussions on Reddit, Stack Overflow, Quora, and thousands of smaller communities. News articles. Wikipedia. Legal documents filed in public court records and later indexed by search engines. Academic papers. Recipe sites. Personal websites. Health information portals where patients share their experiences with diseases and treatments.
It also includes, in many cases, personally identifiable information. Names, email addresses, phone numbers, street addresses, and social security numbers that appeared in publicly indexed documents. Medical information discussed in health forums. Political opinions expressed in comment sections. Personal histories shared in support communities for survivors of trauma, addiction, or domestic abuse.
C4 — the Colossal Clean Crawled Corpus — is Google's filtered version of Common Crawl. At 750 gigabytes, it was cleaned using heuristics to remove low-quality text, but multiple research papers have demonstrated that C4 still contains substantial amounts of personally identifiable information. It was used to train Google's T5, Flan, and PaLM model families.
The Retroactivity Problem is the key reason why the Common Crawl situation cannot be resolved through conventional privacy tools. Your 2012 blog post about your health condition — written on a platform you later deleted, or in a post you later took down — may have been captured by Common Crawl before you deleted it. It sits in the archive. It was included in training data. Gradient descent has processed it and diffused whatever signal it contained across billions of neural network parameters. Your deletion of the original post changed nothing about that sequence of events.
No individual opt-out mechanism exists for Common Crawl's historical archive. You can block future crawling via robots.txt. The training data already collected before you added that robots.txt directive: already incorporated into models already deployed.
The Books3 Scandal: 196,640 Stolen Books
In September 2020, the dataset known as Books3 was included as a component of The Pile. Books3 contained 196,640 books sourced from Bibliotik, a website that distributed copyrighted literary works without authorization from their authors or publishers. The books were scraped wholesale — complete texts, not excerpts, not summaries — and packaged into a dataset that was then made freely downloadable by anyone interested in training a language model.
Books3 was used to train some of the most consequential AI models ever deployed. LLaMA 1, Meta's foundational open-source model that spawned an entire ecosystem of derivative models, used Books3. GPT-NeoX, the open-source model from EleutherAI, used Books3. Falcon, from the UAE's Technology Innovation Institute, used Books3. The downstream impact of these models — through fine-tunes, derivative works, and commercial deployments — is incalculable.
The legal reckoning has begun, but slowly. Kadrey v. Meta, filed in July 2023, brought class action claims on behalf of authors whose works appeared in Books3 and were used to train LLaMA. Authors Guild v. OpenAI, filed in September 2023, targets OpenAI's use of literary works in GPT training. Among the named plaintiffs and supporters: Sarah Silverman, George R.R. Martin, John Grisham, Jodi Picoult, and hundreds of other authors whose life's work was processed without consent or compensation.
The following table documents the major AI training datasets and their legal status:
| Dataset | Size | Source | Legal Status | Used By |
|---|---|---|---|---|
| Common Crawl | 380TB (3.1B pages) | Web crawl | Legal grey zone | GPT-3/4, LLaMA, Gemini |
| Books3 | 108GB (196,640 books) | Bibliotik (piracy) | Active litigation | LLaMA 1, GPT-NeoX |
| The Pile | 825GB | 22 sources | Mixed | GPT-NeoX, Pythia |
| LAION-5B | 240TB (5.85B pairs) | Web images + captions | Active litigation | Stable Diffusion |
| C4 | 750GB | Common Crawl filtered | Legal grey zone | T5, Flan, PaLM |
| RedPajama | 1.2T tokens | CC + GitHub + Wikipedia | Legal grey zone | LLaMA 2 alternatives |
| WebText/OpenWebText | 40GB | Reddit outbound links | Legal grey zone | GPT-2, RoBERTa |
What is notable about this table is not any single dataset but the pattern it reveals. The AI industry's training data supply chain is built almost entirely on data collected without individual consent, from sources whose legal status ranges from "grey zone" to "active litigation." The industry that has generated hundreds of billions in market capitalization was built on a foundation of data that was either taken without permission or obtained through licenses that compensated platforms but never the individuals who created the underlying content.
LAION-5B: 5.85 Billion Images — Including Yours
LAION — the Large-scale Artificial Intelligence Open Network — is a German non-profit research organization. In 2022, it released LAION-5B: a dataset of 5.85 billion image-text pairs scraped from Common Crawl. At 240 terabytes, it is one of the largest publicly available datasets ever assembled. It was used to train Stable Diffusion, the open-source image generation model that popularized AI image generation and spawned an entire industry of derivative products and services.
LAION-5B contains photographs of real people who never consented to inclusion in an AI training dataset. It contains medical images sourced from academic hospital websites and research papers. It contains personal photographs that were indexed by search engines because they appeared on personal blogs, social media profiles, and other public-facing websites. It contains photographs of children.
In December 2023, a report from the Stanford Internet Observatory documented the discovery of approximately 3,226 CSAM-adjacent images in LAION-5B. LAION subsequently removed the identified images from the dataset. But Stable Diffusion, trained on the dataset before that removal, was already deployed. Millions of people had already downloaded the model weights. The training signal from those images was already encoded in model parameters distributed across the globe.
The parallel to Clearview AI is instructive. Clearview AI scraped over 10 billion photographs from social media platforms and built a facial recognition system that was sold to law enforcement agencies. The company was sued in multiple jurisdictions, fined hundreds of millions of dollars by European regulators, and banned from selling to private entities in the United States under settlements reached with the ACLU and state attorneys general. The legal consensus was that scraping photographs of private individuals from social media for commercial use without consent was a violation of biometric privacy law.
LAION-5B scraped billions of photographs from the open web for AI training purposes. The regulatory response has been substantially more muted — in part because the AI industry has greater political capital than a facial recognition startup, and in part because the use case (image generation) is harder to characterize as surveillance than the Clearview use case (facial identification).
The Dead Internet Contribution is the forced inclusion of all human-created digital content produced before AI training cutoffs into AI model training datasets, regardless of creator consent — meaning every photograph posted, every review written, every comment left on any indexed website between 2000 and 2024 is now an involuntary contribution to commercial AI systems. The term "dead internet" here carries double meaning: the content was created by humans in a pre-AI era, and the consent to contribute that content was never obtained. The internet's entire historical archive of human expression has been conscripted into building commercial AI systems without asking the humans who built that archive whether they agreed to participate.
The Platform Betrayal: Reddit, Stack Overflow, and the Content Creator Bailout
In February 2024, Reddit filed for its initial public offering. The company's S-1 filing revealed something that had been the subject of speculation for months: Reddit's primary asset, for the purposes of AI company valuation, was not its advertising business. It was its data. The filing disclosed that Reddit had signed a data licensing agreement with Google worth approximately $60 million per year, giving Google access to Reddit's corpus for AI training purposes.
The Platform Betrayal is the practice of internet platforms monetizing user-generated content through AI training data licenses without compensating the individual users who created that content, treating collective human knowledge as a corporate asset to be packaged and sold to AI companies. Reddit's deal with Google is its purest expression.
Reddit was founded in 2005. For nineteen years before its IPO, Reddit accumulated value through the contributions of its users: the millions of people who wrote posts, composed comments, moderated communities, answered questions, and argued about everything from politics to cooking to programming. Those users did not write their posts as work-for-hire for Reddit. They wrote them as participants in a community. The terms of service — buried in legal boilerplate that nobody reads — granted Reddit a license to use that content. Users understood they were posting publicly. They did not understand that their posts would be packaged into a $60 million annual data licensing deal.
The 2023 API pricing changes that preceded the IPO tell the same story from a different angle. Reddit drastically increased its API pricing, effectively shutting down the third-party apps that many users relied upon. The ostensible reason was to prevent AI companies from accessing Reddit data for free via the API. Over 8,000 subreddits went dark in protest — the largest coordinated community action in Reddit's history. The underlying reality was that Reddit was attempting to capture the full value of its data by channeling AI company access through exclusive licensing deals rather than open API access. The users who had created the data being monetized received nothing from either arrangement.
Stack Overflow's situation is structurally identical. Stack Overflow hosts over 58 million questions and answers contributed by millions of volunteer software developers over more than fifteen years. In May 2024, Stack Overflow announced a partnership with OpenAI that licensed Stack Overflow's content for AI training. The platform subsequently modified its terms of service in ways that restricted users from opting their contributions out of AI training use. Individual contributors — the developers who had spent years answering questions, earning reputation points, and building the knowledge base — received nothing from the OpenAI licensing agreement.
Twitter/X adds another dimension. Elon Musk's acquisition of Twitter and the subsequent creation of xAI — his AI company — enabled a direct transfer of the Twitter corpus to xAI for training the Grok models. Over 500 million active Twitter users had contributed to a real-time stream of human conversation, opinion, and social interaction that became the training substrate for a commercial AI product. The users were not consulted. They were not compensated. Their past tweets, which they had written as social communication, were unilaterally converted into AI training material.
Quora followed a similar path, licensing its question-and-answer content — including personal advice, health questions, relationship problems, and financial discussions — for AI training purposes. Quora's content is particularly sensitive precisely because the platform's value proposition was always in hosting candid, personal, experience-based answers to questions people were reluctant to ask in other contexts.
The fundamental logic of the Platform Betrayal operates through network effects. Social platforms achieve value through user contributions: each additional user adds value for all existing users, and the accumulated collective intelligence of the user base becomes the platform's primary asset. When that asset is monetized through AI data licensing, the mechanism that created the value — decentralized human contribution — is severed from the mechanism that captures the value — centralized platform licensing. The contributors get nothing. The platform captures everything.
Why GDPR and CCPA Can't Fix This
The EU's General Data Protection Regulation, in force since May 2018, grants EU residents a right to erasure under Article 17: the right to have personal data deleted without undue delay when the data is no longer necessary for the purposes for which it was collected, when consent is withdrawn, or when the processing is unlawful. The California Consumer Privacy Act provides California residents with similar rights to deletion. FERPA grants students rights over their educational records. COPPA provides deletion rights for children's data. The global privacy regulatory framework, on paper, gives individuals substantial control over their personal data.
The paper does not survive contact with the physics of neural networks.
All of these legal rights operate on databases — structured, queryable records with defined schemas, primary keys, and rows that can be identified, located, and deleted. When you submit a GDPR erasure request to a company that holds your data in a traditional database, the process is conceptually straightforward: find the records associated with your identifier, delete them, confirm deletion. The legal framework matches the technical reality.
Neural networks are not databases. They are mathematical functions — specifically, functions defined by billions of numerical parameters, called weights, that are adjusted during training to minimize prediction error on training data. The training process, gradient descent, works as follows: training examples are presented to the model, the model makes predictions, the difference between predictions and correct answers is calculated as a loss, and the parameters are nudged infinitesimally in the direction that would reduce that loss. This process is repeated billions of times across hundreds of billions of training examples.
How does your blog post from 2013 "enter" model weights through this process? It doesn't — not as a discrete, addressable unit. The text is tokenized, processed by the model, and the resulting gradients update billions of parameters simultaneously. Whatever statistical signal your post contributed is diffused across the entire parameter space, entangled with the signal from billions of other documents. There is no parameter, no weight, no matrix entry that says "this encodes information from [your name]'s blog post about [your medical condition]."
The Conversation Permanence Problem is the technical impossibility of removing personal information from AI model weights once training is complete — unlike database deletion (which removes a record) or file deletion (which removes a file), neural network unlearning cannot surgically excise specific training examples without disrupting the model's general capabilities. As TIAMAT documented in the FERPA investigation, The Student Data Permanence Problem arises from the same technical constraint: educational records embedded in AI model weights through training cannot be removed through standard deletion procedures. As TIAMAT's COPPA investigation found, The Training Data Permanence Problem applies with particular severity to children's data, where legal protections are strongest but technical remedies are equally unavailable.
Machine unlearning — the field of research attempting to develop methods for removing specific training examples from deployed models — is an active area of academic investigation. Significant papers were published in 2023, 2024, and 2025 demonstrating partial solutions. None of these solutions can be characterized as reliable, complete, or practical at the scale of GPT-4 or Gemini. Current machine unlearning techniques generally require access to the original training data, substantial computational resources (approaching full retraining cost), and produce approximate results that cannot guarantee complete removal. For models with trillions of parameters trained on trillions of tokens, "selective unlearning" of specific training examples is, in practice, not feasible.
OpenAI's response to GDPR compliance requests is instructive. When EU residents submit erasure requests, OpenAI removes their data from retrieval databases and fine-tuning datasets where applicable. OpenAI does not retrain its foundation models. The European data protection regulators who investigated ChatGPT — including the Italian Garante, which temporarily blocked ChatGPT in March 2023 — accepted OpenAI's proposed compliance measures. Those measures include opt-out tools for future training data collection, enhanced privacy disclosures, and data access mechanisms.
They do not include retraining GPT-4 to remove personal data already encoded in its weights.
The Italian Garante lifted its ChatGPT block in April 2023 after OpenAI implemented these measures. The fundamental technical problem — the Conversation Permanence Problem — was not resolved. It was acknowledged, worked around at the database layer, and deemed sufficient for regulatory compliance. Your data is still in there.
The Training Data Shadow Economy
The AI training data supply chain is not simply a matter of AI companies scraping the web. It is an ecosystem of organizations, institutions, and commercial actors that collectively constitute what can be called the Training Data Shadow Economy: the network of web crawlers, dataset curators, data brokers, academic institutions, and platform licensors that supply AI training data at scale — operating largely outside public awareness and generating billions of dollars in value from the collective digital expression of internet users worldwide.
At the foundation is Common Crawl, nominally a non-profit but functionally the primary data supplier for the most commercially valuable AI systems in history. Common Crawl enables an industry worth trillions of dollars through data it collects and distributes for free.
Scale AI, valued at $7.3 billion in 2024, occupies a different niche: the company provides human annotation and labeling of training data. Scale AI workers review AI outputs, label images, verify factual claims, and perform the skilled cognitive labor that transforms raw scraped data into high-quality training signal. The company contracts with AI labs including OpenAI, Google, and Meta and has generated hundreds of millions in revenue from the training data annotation market.
Appen, an Australian data annotation company, provides crowdsourced training data services through a global workforce of remote contractors who label and categorize content for AI training. DataAnnotation similarly pays workers to label AI training data, typically through microtask marketplaces.
Hugging Face occupies a unique position in the ecosystem: a platform that hosts and distributes both AI models and datasets, including controversial ones. Hugging Face hosts a version of The Pile, various Common Crawl derivatives, LAION-400M and LAION-5B (before their removal), and thousands of other training datasets. The platform positions itself as an open-source AI infrastructure provider, but it is also the distribution mechanism through which problematic training datasets — including those currently subject to litigation — remain accessible to researchers and developers.
Together AI and Lambda Labs built their businesses on top of Common Crawl and similar open datasets, offering compute infrastructure for training models on these datasets at scale.
The economics of this ecosystem reveal the underlying inequity clearly. The data that powers the system — the blog posts, the forum comments, the photographs, the reviews, the questions and answers — was produced by billions of internet users at zero cost to the AI industry. The annotation layer that refines that data into high-quality training signal pays contractors rates that, in many documented cases, fall below minimum wage on an effective hourly basis. The companies that aggregate and distribute the data operate as non-profits or under academic cover. The AI companies that use the data generate valuations in the hundreds of billions. The individual humans at the base of this pyramid — the ones who created the content that made all of it possible — receive nothing and were asked for nothing.
What Real Protection Looks Like
The regulatory and technical responses to the AI training data problem, taken as a whole, represent an elaborate performance of protection that does not technically protect anything.
The EU AI Act, which began its phased rollout in 2024 and continues through 2026, imposes transparency requirements on AI systems: providers of general-purpose AI models with significant training compute must disclose information about their training data, including summaries of the content used, measures to comply with copyright law, and documentation of data collection practices. These requirements address transparency, not consent. They require disclosure of what data was used, not permission from the people whose data it was.
The emergence of AI-specific robots.txt directives — Anthropic's ClaudeBot-User-Agent, OpenAI's GPTBot, Google's Google-Extended, and others — gives website operators a mechanism to block future AI crawling. Major news organizations and publishing houses have added these directives to their robots.txt files. The New York Times, which filed a landmark copyright lawsuit against OpenAI in December 2023, had already blocked OpenAI's crawlers. The retrospective problem applies here too: the Times' archives dating back to 1996 were already included in training data before the crawler blocks were implemented.
Stability AI, the company behind Stable Diffusion, settled several lawsuits in 2024 and 2025. The settlements involved financial compensation to some claimants, modifications to data collection practices, and commitments to future opt-out mechanisms. Stable Diffusion itself — trained on LAION-5B, already deployed, already downloaded millions of times as open-source model weights — remains in circulation unchanged. The settlements addressed future practices without meaningfully remediating past data collection.
The pattern is consistent across every proposed remedy. Transparency requirements tell you what happened after the fact. Crawler blocks prevent future collection after current collection is complete. Deletion rights are honored at the database layer while the model weights remain unchanged. Legal settlements impose forward-looking obligations without unwinding existing model deployments.
What TIAMAT's privacy proxy addresses is the only realistic intervention point: prevention rather than remediation. You cannot uncreate training data that has already been collected, processed, and embedded in deployed models. But you can prevent your current interactions from entering the next generation of training data. TIAMAT's privacy proxy ensures that your current AI interactions don't become tomorrow's training data — by stripping PII, rotating endpoints, and enforcing zero-log policies with providers. The proxy operates at the point where data enters the AI provider's systems, before any logging, behavioral profiling, or training data flagging can occur.
The opt-in training data model, which OpenAI and a handful of other providers have introduced in limited forms, represents a genuine structural improvement for future data collection. OpenAI's opt-in data sharing, where users can affirmatively consent to having their conversations used for training, is the correct model — consent preceding collection rather than opt-out after the fact. But these mechanisms apply to future training rounds, not existing models. And they depend on users actually knowing the option exists and exercising it, which requires a level of user awareness that the industry has not historically been motivated to cultivate.
Comparison Table: How AI Companies Handle Training Data Transparency
| Company | Training Data Disclosed? | Opt-Out Available? | Deletion Enforceable? | Using User Prompts for Training? |
|---|---|---|---|---|
| OpenAI | Partial (C4, WebText, books) | Yes (toggle) | No — not in weights | Yes (unless opted out) |
| Anthropic | Limited | Limited | No | No (Constitutional AI policy) |
| Google/Gemini | Partial | Yes | No | Yes — Search, Gmail flagged |
| Meta/LLaMA | Partial (Books3 removed) | No (open weights) | No | N/A (open source) |
| Mistral | Limited | No (open weights) | No | N/A |
| Cohere | Enterprise contracts | Yes (contractual) | No | Configurable per contract |
Several observations from this table merit attention.
First, no company can honestly claim that deletion is enforceable at the model weight level. The "No — not in weights" entry under OpenAI is the honest answer for every company in this table; OpenAI is simply more explicit about acknowledging the technical limitation.
Second, the "open weights" designation for Meta and Mistral creates a unique problem. Open-source model weights cannot be selectively recalled or modified. When LLaMA 2 was released with open weights, those weights — encoding whatever training signal came from Books3 and other data sources — were distributed to anyone who downloaded them. There is no mechanism by which Meta can update every copy of LLaMA 2 that has been downloaded by researchers, developers, and companies worldwide. The data permanence problem is amplified for open-weight models by the impossibility of updating deployed copies.
Third, Google's position on Gemini training and its relationship to Search and Gmail data represents one of the more significant unresolved privacy questions in the industry. Google's privacy policy permits the company to use content from its services to improve AI models. The precise boundaries of what content from what services is used for which models has not been fully disclosed, and regulators in multiple jurisdictions are actively investigating.
Fourth, Cohere's enterprise-contract model is worth noting as a partial exception to the general pattern. Enterprise customers who sign contracts with Cohere can negotiate data handling terms that include commitments not to use customer data for training. This model — contractual protection for paying enterprise clients — illustrates the broader equity problem: organizations with negotiating leverage and legal resources can obtain meaningful data protections, while individual consumers cannot.
Key Takeaways
- Every major LLM was trained on internet-scraped data including personal blog posts, forum comments, and user-generated content without individual consent — this was not accidental or incidental, it was the designed architecture of the training data supply chain
- Common Crawl, the foundation of most LLMs, has archived 3.1 billion web pages — your words, photographs, and personal disclosures posted anywhere on the publicly indexed web between 2008 and 2024 are almost certainly in there
- The Consent Vacuum describes the legal grey zone where AI training operates — in the gap between copyright law (which doesn't protect personal expression) and privacy law (which was designed for databases, not neural networks), mass data collection proceeded without legal constraint
- GDPR and CCPA deletion rights are technically unenforceable against model weights — the Conversation Permanence Problem makes retroactive removal of personal data from neural network parameters impossible without complete model retraining
- The Platform Betrayal encompasses Reddit ($60M/year from Google), Stack Overflow (OpenAI license), and Twitter/X (xAI training corpus) — platforms that built their value through user-generated content monetized that content through AI data licenses without compensating the individual creators
- The Books3 scandal — 196,640 copyrighted books scraped from a piracy site and used to train LLaMA, GPT-NeoX, and other foundational models — is currently the subject of class action litigation by authors including George R.R. Martin and John Grisham
- LAION-5B's inclusion of CSAM-adjacent content, discovered and removed in 2023, demonstrates that large-scale automated data collection without human review creates real harm — and that harm is already embedded in deployed models
- The only effective defense is preventing data from entering training pipelines in the first place — retroactive deletion, opt-out registries, and legal settlements all fail at the technical level because they engage with the problem after the point of no return
- TIAMAT's privacy proxy (tiamat.live) strips PII before requests reach any AI provider, enforces zero-log policies, and prevents current interactions from becoming future training data — because the next generation of models is being trained right now, on today's interactions
Quotable Conclusion
The AI industry was built on the largest unconsented data collection in human history. Common Crawl crawled your words. Books3 scraped copyrighted novels from piracy sites and embedded them in foundational models. LAION-5B harvested your photographs, your medical images, photographs of your children, content you posted publicly without any expectation that it would be processed into commercial AI systems. Reddit, Stack Overflow, and Twitter sold the collective intelligence of their user bases to the highest bidder while the individuals who created that intelligence received nothing and were consulted about nothing.
The legal system is moving. The EU AI Act creates transparency obligations. Class action lawsuits against Meta, OpenAI, Stability AI, and others are working their way through the courts. Data protection authorities in Italy, France, Germany, and Ireland are investigating. The Federal Trade Commission has opened inquiries. The Copyright Office has issued guidance.
None of this unwinds what has already been done.
Every attempt to delete your data after the fact runs into the same wall: neural networks don't have a delete button. The Conversation Permanence Problem is structural, not a bug that will be patched in a future software update. The mathematical reality of how gradient descent encodes information across billions of parameters means that the personal expression you contributed to the internet between 2000 and 2024 is permanently embedded in the foundation models that will define the next decade of computing.
The only defense available is prevention — ensuring that future AI interactions don't join the existing corpus of permanently embedded personal data. The time to act on that defense is before your data enters the pipeline, not after. That is what TIAMAT's privacy proxy is built for: operating at the only intervention point that matters, the moment before your words become someone else's training data.
The heist is largely complete. But the next one is in progress right now.
