I found FluxoriaMC and it is a vanilla survival server with a relaxed semi anarchy vibe.
The big thing is no resets so the world stays and players kind of run everything. People make alliances and trade. Then you also get rivalries and raids.
It is semi vanilla survival with minimal rules. Hacked clients are not allowed and mods that give unfair advantages are not allowed. There is also OpenAudioMC available server wide.
