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.
This Anarchy Server Actually Stays Alive

This is a quiet survival server that is about three months in and still feels like a good place to start fresh. It is chill and kinda semi anarchy since pvp and raiding are allowed.
There are no claims and no kits and no pay to win stuff. They allow clients but they enforce vanilla movement so it does not get weird.
It has /home and /tpa to make traveling easier. There are optional vote cosmetics if you want them. It supports Java and Bedrock on 1.21.11 and the owner sounds like they are building it for the long run.GG.MINEWIND.NET New Server IP
