Ah yes, one more comment. If I were a dad of one of these girls I'd be furious at my DAUGHTER FOR POSTING THESE PICTURES ON FACEBOOK, not the guy who posted them on his site. Guys are guys, and all guys (at least heterosexual guys) like pictures of attractive women, even dads.
I recently saw this article as it links to my site. For the record the site has been toned down a TON. Second of all, I remove any post when a girl has contacted me and wishes it taken down. Thirdly, I've received letters from girls actually thanking me for posting them. As far as the legal implications? That's up to you guys to debate but if the girls aren't complaining I'm not sure you guys should be. I mean no one harm. But you just keep writing about all things Facebook, use the word FACEBOOK as often as possible and keep building that traffic up.
