Reported at CBC News, a 27 year old male that went by the in-game name Ricdic decided to "skim off the top" at his position as head of EBank, one of the largest banks in EVE Online. Ricdic "skimmed off the top" to the tune of 200 billion ISK, or 8 percent of the total funds that the bank had been holding. Word spread quickly in EVE Online, resulting in a virtual bank run.

The story doesn't end there.
Ricdic went on to trade the virtual money for real world cash, using it to pay off medical bills and other expenses. All in all, Ricdic was able to net himself about $5,000 USD.
According to the CBCNews article, Ricdic appears unrepentant of his actions, stating, "If I had to do it again, I probably would've chosen the same path."
Ricdic's actions while in the game world were actually not a violation of the rules. As most players know, the world of EVE Online is rife with such scandals. The problem was the fact he then exchanged the money for real world cash, a big no-no according to CCP Games. This has resulted in a permananet ban from EVE Online for Ricdic.
