Quick fix for current spam deluge

If you use Grease Monkey or similar, you can use this user script to filter out the current spam posts in your feed:

// ==UserScript==
// @name     dev.to spam filter
// @version  1
// @include  http*
// @match    *://dev.to/*
// @grant    none
// @run-at   document-end
// ==/UserScript==

const dev_posts = document.body;

const config = { attributes: false, childList: true, subtree: true };

const callback = function(mutationsList, observer) 
{

  for(const mutation of mutationsList) 
  {
    if (mutation.type === 'childList') 
    {
      let posts = document.querySelectorAll('article');

      posts.forEach(post =>
      {
        const title = post.querySelector('.crayons-story__title a');
        if(title.innerHTML.replace(/\n/g, '').match(/customer.*care.*number/i))
        {
          post.parentElement.removeChild(post);
          console.log('removed post')
        }
      });
    }
  }
};


// Create an observer instance linked to the callback function
const observer = new MutationObserver(callback);

// Start observing the target node for configured mutations
observer.observe(dev_posts, config);
Enter fullscreen mode Exit fullscreen mode

Obviously this is a temporary work around while smarter people look at real spam filters, but my feed was unbrowseable :D

You'll need to do a hard refresh for the filter to kick in.

Thanks to MDN for the mutation observer code.

I've put it into a Gist if people want to offer up improvements.

Updated to cover when "customer care number" has things other than spaces in it.

This post blew up on DEV in 2020:

🚀⚙️ JavaScript Visualized: the JavaScript Engine

As JavaScript devs, we usually don't have to deal with compilers ourselves. However, it's definitely good to know the basics of the JavaScript engine and see how it handles our human-friendly JS code, and turns it into something machines understand! 🥳

Happy coding!
