I found a vanilla anarchy style survival server with minimal rules and a lot of freedom. It has been running for almost a year so it feels like a real long term world where people actually build and fight.
It is called NoHackAnarchy and the big thing is it is anarchy but without hacked clients or cheats. Xray is not allowed even with resource packs. They also do not allow exploiting server vulnerabilities or trying to crash the server or lag it out.
Macros and automation tools are prohibited too. Chat spam can get you auto kicked. You can join on Java from 1.13 to 1.21.x and Bedrock players can get in as well.
