I did notice @erotic seemed to be posting a lot of copyrighted images. I saw some that said PLAYBOY right on them. That's the only reason I could see though. And the first image... what good is NSFW if it shows a pornographic image in the thumbnail in the list. Though I think the real issue is getting flagged for monetary, and reputation hit. So I guess I have a simpler answer... "I don't know." :P
