Yes, I know this is a little old (posted August 22, 2006), but I found it interesting nevertheless.
...a guy named "cally", who ran a corporation, a player-operated bank called "Eve Intergalactic Bank". Over the course of four months, hundreds of players deposited money in his bank, which offered interest, loans and insurance like every other ordinary bank. Except for the fact that one day, cally decided to grab all the money that was deposited and fly off to space with an alleged total sum of 790 billion Isk. In real life, this would translate to $170,000 - quite possibly the biggest MMO scam ever conducted.
