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

I found a server that is meant to be 18 plus only and it takes the adult only rule seriously. The owner said they finally had a kid sneak in and it caused a big mess so they are trying to stop it from happening again.
The server has players who keep to themselves sometimes and build a base and only talk when they feel like it. But the staff will step in if someone seems shady like asking about xray or anticheat or if stealing is allowed.
Now the rules got stricter and you have to use voice chat to stay. If you want an adults only place with active moderation and clear rules this server is aiming for that vibe.GG.MINEWIND.NET New Server IPMinimal Rules Vanilla Anarchy No Cheats
This is a vanilla anarchy style server with minimal rules and a lot of freedom. It has been running for almost a year so the world feels lived in.
The big thing is it is no cheats allowed. That means no hacked clients no xray even with resource packs no macros and no automation tools. They also do not allow exploiting server vulnerabilities or trying to crash the server or lag it on purpose.
Chat spam gets handled with auto kicks so it does not turn into total noise. It supports Java from 1.13 to 1.21.x and it also supports Bedrock and even console players through adding a friend.GG.MINEWIND.NET New Server IP
