in this form it has been likened to counterfeiting except with reduced risk. Response As with other exploits, a common response to duping is to ban the involved players. Banning players for duping can be controversial though depending on how the game developer determines a player to be "involved" in the dupe. In Star Wars Galaxies some players learned how to dupe the currency. Sony Online Entertainment (SOE) banned players who possessed duped currency. It is alleged that people who were not directly involved in the exploit, but who accepted duped currency in legitimate trade were also banned. In reaction to what was perceived to be an unjust punishment, several players joined a mass demonstration at a central location in the game world. SOE responded to the disruption caused by the large gathering by teleporting all player characters involved away from the demonstration area. A popular online urban legend is that many player characters were teleported into space, essentially killing them. Although evidence as to whether or not this occurred cannot be substantiated, it has been voiced in many popular gaming avenues, such as Penny Arcade. Another method to mitigate the effects of duping would be a rollback, in which game data is reset to an earlier data backup prior to the first known instance of duping. This can include all game data or be limited to specific items, characters, or other means determined to be involved in the duping. Significant rollbacks can be a highly unpopular decision with the players and is best done before much time has passed. Alternately, SOE was able to track and remove the duped currency in EverQuest II. The virtual world designers may find more natural ways to remove the offending currency or items from the game. In Star Wars Galaxies the legitimate economy had been losing money faster than money was being created due to a variety of money sinks. After the dupe bug was fixed and trillions of potentially duped in-game currency deleted, the designers decided to let the economy to continue running at a net loss until the levels could return to normal. An immediate, although often temporary, step to prevent further issues from duping calls for aspects of the game to be disabled until the exploit can be addressed permanently. SOE stopped Station Exchange auctions to prevent the dupers from selling the illegitimate EverQuest II currency. Other notable cases The
