Man, been wondering the same thing! However, I believe these sites employ some kind of like-hijack as you reach the page. I kind of clicked on one of them. Or not even that, I saw some friend liking this crap, it said the website in the post so I copy-pasted it in the address bar. Saw crap. Left. Safe-checked my profile. Nothing. But like 15 mins later I checked my profile again, bam, there it was. I had liked this friggin crap by directly visiting this site! Now I can't remember which one as I camped out on the newsfeed and marked all that crap as spam..
