Keyboard macros have in more recent times come to life as a method of exploiting the economy of massively multiplayer online role-playing game (MMORPG)s. By tirelessly performing a boring, repetitive, but low risk action, a player running a macro can earn a large amount of the game's currency or resources. This effect is even larger when a macro-using player operates multiple accounts simultaneously, or operates the accounts for a large amount of time each day. As this money is generated without human intervention, it can dramatically upset the economy of the game. For this reason, use of macros is a violation of the TOS or EULA of most MMORPGs, and administrators of MMORPGs fight a continual war to identify and punish macro users
