Anarchy servers are survival multiplayer servers with little to no rules and minimal moderation, where griefing, stealing, scams, and PvP are usually allowed. They often have no land claims, no resets, and a long-lived world, so players rely on secrecy, alliances, and stashes to survive. Many also end up with a meta around exploits, hacked clients, and dupes, depending on how strictly the server enforces vanilla mechanics.
