Duping (gaming)

Duping refers to the practice of use a bug in a video game to illegitimately create duplicates of unique items or currency in a persistent online game, such as an MMOG. Duping can vastly destabilize a virtual economy or even the gameplay itself, depending on the item duplicated and the rate at which duplication occurs. Modern persistent world games include automated detection of duping. Duping is considered to be a game cheat.
