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

Yep, seems like a total waste of time. The people scraping will spend the necessary time to get around this (and then distribute that knowledge to the masses) so it seems like a pointless arms race. Facebook employees could better use their time on developing actual features that bring value.
