I found this survival server that tries to stay as vanilla as possible and it is all about freedom.
There are no gameplay rules and no admins watching over you. There are no land claims and no protection so griefing and PvP can happen anytime. Cheating and building and basically everything goes.
It also says there are no server sided dupes and there are no world resets so the world keeps its history.
The server has been running since April 2021 and it is on 1.21. You can still join from 1.17 up to 1.21.11.
