Those ads with all the pics and interesting titles?
 

I've been seeing a lot of ads that have maybe 2 rows of 4 pics each and some interesting titles like "top 10 dirty girls" and "15 ways to.....".

What's up with them? are any of them pay per click? They look like they're content of the sites they're on, but they link out. I'd love ads like that, non-nude, that pay per click. Do these exist?
