A door closer is a type of griefer that likes to prevent players from leaving or entering a building. These players are often viewed as some of the most annoying players in the game. Some of these players find amusement in other's frustration, or they may be helping thwart the macroing problem by trapping bots inside or outside of a specific building. Quite often the griefers would demand unreasonable amounts of money to stop. Before the "pure essence" update, trapping bots using Aubury's door was something of a sport, particularly if they were under attack.
