FBI Investigates 'Revenge Porn' Website Founder

James McGibney, a former marine and founder of BullyVille.com, told "Nightline" he did a public service by shutting down Moore, something he said even the government wasn't able to do. However, several critics called the move a media stunt because the re-direct from IsAnyoneUp.com occurred less than a week after BullyVille.com launched, and BullyVille.com received two million visitors from it.

McGibney denied that shutting down IsAnyoneUp.com was for personal gain.

"Do you know what kind of base [Moore has], the subscriber base?" he said. "It's not the type of people I want on BullyVille."

But BullyVille.com isn't McGibney's only website. His bread and butter is CheaterVille.com, a website where anyone can accuse someone of cheating on a spouse or a partner and post it anonymously. But McGibney said CheaterVille.com is nothing like Moore's "revenge porn" website.

"There is no doubt I believe in what I'm doing or I wouldn't do it," McGibney said. "[CheaterVille.com] was not started for revenge or for malicious intent. It was designed to warn people, and I'm never going to change that thought because that's what I believe in."

Moore may have turned humiliation into a business model, but he hasn't cornered the market on getting even. Today, revenge is something he is trying to avoid.
