Looking for a way to get revenge on your ex-girlfriend? Or maybe you're hoping to scare your teen into knocking off the sexting? Perhaps you caught your boyfriend sending pics of his penis to some other chick? Send your images to IsAnyoneUp.com!

Okay, no, don't. The site is the Internet's version of the cool kids in school grabbing the dorky band nerd in the playground, pulling his pants down and making fun of him. Only in most cases on this site, the dorky band nerd pulled his pants down himself, took a picture and sent it to someone he didn't think would share it with anyone else.

Enter Hunter Moore and IsAnyoneUp.com. Moore started his site in Sydney, Australia, and is now living in San Francisco. He receives naked (or mostly naked) images from people's exes (and sometimes the people themselves) and posts them alongside the person's Facebook profile without censoring personal information.

He's been cursed at, yelled at, harassed and even stabbed over the images he's posting online without permission. And now, Facebook is even on the case. They've sent Moore a three-page Cease & Desist letter demanding the immediate removal of all Facebook content from the site. But Moore remains unfazed.

“I replied with a picture of my dick,” Moore told Gawker in a phone interview. “I'm not a virgin to cease and desists—I get about a million a day. I think [Facebook] is under pressure from users to do something about me ... I don't give a fuck. I'm never going to stop.”

His mission? To get you to stop sexting. Yeah ... That'll happen.
