I found a small anarchy server that has been running on the same world for months and it is not doing resets or seasons. There is no fresh wipe hype and it is not pay to win. It feels like a place that just keeps going no matter what.
The map is meant for long term builds and the world border is huge so people can hide or hunt for bases. The server says it holds around 20 TPS and it is hosted on EU dedicated hardware.
It is semi vanilla with only a couple helpers like TPA and vote homes. Dupes are patched and most exploits are allowed but movement stuff and xray are not.
Spawn is not safe at all and people will try to trick you. You can lose everything fast or you can build something that actually lasts. There is also a practice PvP server running alongside it for fights and warmups.
