I found a small anarchy server that has been running on the same world for about 4 months and it is still going. It is the kind of place that does not do seasons and does not do wipes just to bring hype back.
It is mostly vanilla but it has TPA and vote homes only. Dupes are patched and most exploits are allowed but movement hacks and xray are not.
The world border is huge at 1m by 1m and the server is hosted in the EU on a dedicated machine. It usually sits around 20 TPS and there are like 0 to 9 players daily.
Spawn is not safe and people will lie to you so you can lose everything fast. If you stick it out you might actually build something that stays there.
