The unemployed thieves stole the login and password of a player, accessed his account, and sold off his inventory to the tune of $6,405. They were caught soon after and will face not only jail but fines for the crime.
Late last year 10 Chinese thieves were caught stealing World of Warcraft accounts and selling players' possessions. They too received about two years in jail and had to cough up fines.
