ABOUT THE WIKI
2builders2tools (2b2t) is a Minecraft server founded in December 2010. 2b2t is the oldest anarchy server in Minecraft, as well as one of the oldest running Minecraft servers of any variety. Additionally, 2b2t's world is one of the longest-running server maps in the game, which has never been reset since its creation. As the server has virtually no rules or authority, griefing and hacking are common amongst players, with no risk of getting banned. The server is permanently set to hard difficulty and player versus player combat is enabled throughout. The server has seen over 724,000 players explore its procedurally generated map, increasing its file size to over 13.3 terabytes. 2b2t has been described in news media as the worst Minecraft server due to its playerbase and culture.
