Yes, instead of doing the right thing and returning the item (”Martin Fury”, an in-game shirt), he kept it and went out on a bit of a killing spree. Because the shirt allowed the wearer to destroy everything within a 30-foot radius instantly, the user – Karatechop – managed to rack up an impossibly impressive set of achievements in the game, including the destruction of the normally-difficult character “Flame Leviathan” in a single blow.

While his account has since been banned, with Blizzard accusing him of cheating to obtain the item, Karatechop maintains that the item was accidentally presented to a guild mate of his by Blizzard, in an official Blizzard email, as part of the restoration process for a hacked character.
