A WoW player living in Indianapolis was arrested after he used in-game chat to threaten to blow up a plane while he is wow power leveling. The eighteen year old later told Johnson County sheriffs that he "was going to board a plane at 7:30 to Chicago and that (he) was going to try and kill as many Americans as possible".
His boasts were spotted by a Blizzard employee who called the police after seeing that the WoW player had made serious threats. When arrested, the man claimed his computer had been hacked into and then explained he had meant the statements as a joke. He had apparently made them because he didn't believe that, contrary to popular belief, that doing so wouldn't alert the police.
A Blizzard representative is quoted as saying that the chat logs were "very serious" and didn't seem to be just jokes however she declined to show the logs to indystar.com. The man's PC was seized as evidence and the cased turned over to the FBI.
The most direct meaning form the accident is that don't threaten to blow up planes in Azeroth. It's not smart. Wow is the place for World of Warcraft Power Leveling and enjoys the adventure. And the US supervision on the internet is much serious.
