who turned this guy in? (Score 1)

Who turned this guy into the cops? NCSoft, the auction site, one of his customers? I hope it wasn't NCSoft who reported a "crime" to the police and then gave them the guy's registration info to bust him. I could understand if one of his customers reported him for fraud and they arrested him for fraud but it says he was arrested for his actions in the game. Doesn't there need to be a law against something before the cops can arrest people for it? What are the Japanese police going to do when I log onto the Japanese L2 servers from the US and start ganking people for items? Try to extradite me?
