I found this semi anarchy SMP that is honestly just pure chaos in a good way. It has this really old map that has been around for more than six years so everywhere you go you find old bases ruins and random projects from different players.

The server is basically classic Minecraft survival with no hacks allowed. Plugins are kept small so it still feels like vanilla. They also have a high mob cap so farms work really well and you can grind mobs and resources like crazy.

You can do pretty much anything here. You can build and make big bases fight other players trade with people or just wander around and explore old history. Griefing is allowed and there is drama and bounties and all that so it really feels like a lawless sandbox.

The community is super weird but in a fun way. There are all kinds of players with funny names and personalities and a bunch of inside jokes. People hang out a lot and there is a tight knit group that plays together all the time. They also run server events with special lore items and they even have a wiki for the server.

There is only one real rule. Do not cheat. If you want a place where anything can happen and the world already has tons of history this server is actually pretty cool.
