AFK Farming
From City of Heroes: Rebirth - Wiki
Definition
AFK Farming is any set of actions where a player can earn certain rewards while not even at their computer (AFK). The game has been designed to eliminate AFK farming of XP and Inf, but it is still the preferred method among players for obtaining certain Achievement Badges.
Note: Using third-party software (bots) to perform actions while away is in violation of the User Agreement and is discouraged.
