MMORPG=>RMT

A farmer is a general term for a MMORPG player who attempts to acquire ("farm") items of value within a game, usually in order to exploit the game's virtual economy. This is usually accomplished by carrying out in-game actions (such as killing an important creature) repeatedly to maximize income. More broadly, the term could refer to a player of any type of game who repeats mundane actions over and over in order to collect in-game items.

A gold farmer is a player who farms items for the sole purpose of sale to other players via an out-of-game venue, such as eBay or IGE (also called RMT - Real-money trading). Since there is significant real-world demand for in-game gold, gold farming sometimes is taken very seriously.
