Anarchy Network is a semi anarchy survival server that tries to feel really close to normal vanilla Minecraft. It has only a few rules and not many changes so most stuff feels like singleplayer but with other players trying to kill you.

The world is huge with a border way out there so people can spread out and build or hide. There are no map resets so anything you build or destroy is meant to stay. Griefing and PvP are fully allowed so you always have to watch your back.

There is no teleporting and no pay to win stuff. The only command they let you use that changes the game is spawn so players who go super far away can still get back to other people. The nether roof is allowed. Phantoms are turned off and only half the server has to sleep to skip the night.

They do block anything that totally breaks the game. Things like exploits lag machines duping and spam are not allowed. Also harassment and racial slurs in chat are not allowed so the chat does not get totally toxic.

The server runs all the time and you can join from lots of Java versions including the newest one. It seems like a good place if you want freedom and chaos but still want some basic limits so the server does not get ruined.
