2b2t (2builders2tools) is a Minecraft server founded in December 2010. It is the oldest and most infamous "anarchy server" in the game. The server has almost no rules, and players commonly engage in griefing, the deliberate destruction or alteration of other players' creations, as well as hacking through modified software to gain an advantage. 2b2t is among few Minecraft servers of any kind established in 2010 that remain active.
