MinecraftOffline is an anarchy server where players can do their thing and the world is meant to last. The map is permanent so builds and damage can stick around for a long time.
It runs on version 1.21.11 and it uses a custom plugin suite. The server is based in Finland so it should feel smoother for players in Europe.
The hardware is listed too so it seems like the owner cares about keeping it stable. If you want a server that sounds serious about uptime and long term chaos this one fits that vibe.

I found Take Out Anarchy and it is a brand new Minecraft server that is ruleless and it is for version 1.21.11.
It is trying to feel like vanilla with zero limitations and it also says there is absolutely zero admin intervention. That means players decide what happens and you just survive however you can.
If you want a no rules place to play and you like chaos this one is looking for players right now.GG.MINEWIND.NET New Server IP
