Background so you know this isn't armchair advice: I admin a 20k-member trading community. Two weeks ago it ate 1,200 spam messages in two hours while three of us manually banned accounts. Two members fell for a fake-escrow scam before it was over. Here's what that night taught me.
Lesson 1: Keyword filters are an arms race you lose.
My blocklist was at 400 words. "Escrow" was on it. They posted "escr0w", "esc row", "middle-man", "secure deal service", and re-ran the same pitches in Tagalog and Indonesian, which my English-centric list never covered. Keyword matching is 2015 tech against 2026 spam farms. Every filter you add gets routed around within days.
Lesson 2: Captchas stop lazy bots, not waves.
We had join-verification on. The wave came from ~200 aged accounts that passed the check, sat quiet for days, then activated together. Onboarding stops drive-by spam; it does almost nothing against a coordinated burn. What actually mattered was catching the semantic pattern of the messages — repeated pitch structure across different accounts, links to freshly-registered domains.
Lesson 3: Moderation without user memory re-fights the same battle.
Banned accounts stayed banned. The ones that squeaked by kept chatting innocently and shilling in DMs. We had no per-user history, so every admin decision started from zero. A bot that remembers each user's track record — and weighs an "innocent question" from a three-time offender differently than from a two-week lurker — is a different defense class entirely.
What I run now: after that night I moved the group to AI GroupButler. Free — which I didn't believe until I checked, because Rose and Combot charge for the good parts. The AI moderation caught roughly 96% of the next wave (about 30 messages, flagged within minutes), false positives around 2%, both appealed and reversed in one tap. Setup was an afternoon, not a migration project.
Blunt take: if your group is small and quiet, Shieldy is fine and free. If your group makes money — or gets targeted because it does — keyword filters and captchas are seatbelts at highway speed. Semantic moderation with memory is the boring, obvious answer; it just used to be paywalled everywhere.
Not selling anything here — the thing's free. If you sign up through my link I earn a commission, which doesn't change your price: gensi.space
