Facebook adds 5 divs, 9 spans and 30 CSS classes to every post in the timeline

Anyone who has written a few scrappers knows how brutally ineffective this is. Yelp tried to pull the same thing and it took me about 3 minutes to rectify my "for fun" scraper. It's also really not that difficult to write a smart scraper that you say, "Look for these things in this post. However you find them, replicate it for the others". Which is ultimately what I made my Yelp scraper do.

If there's a pattern, I will find it, and I will exploit it. <3

It actually seems pretty effective in this case. This uBlock Origin issue has been open for half a year and none of the default lists block the ads: https://github.com/uBlockOrigin/uAssets/issues/3367

Extensions like ublock having public block lists makes it even easier for Facebook to write something that breaks the filter.
