As online games got bigger and more popular, gamemasters' jobs grew to include giving customer service for an online community. A gamemaster in such a game is either a volunteer player that has been there a long time, or someone who works for the game's publisher. They make everyone follow the game's rules by getting rid of spammers, player killers, cheaters, and hackers and by solving players' problems by giving general customer service. For their jobs they use special tools and characters that allow them to do things like teleport to players, make items, and look at logs that record players' actions. Often, players who aren't happy with the game will blame the GMs for any problems. However, this blame is not fair as most GMs are not developers and cannot fix those types of problems.
