I found a public ATM 10 server that started as a friends server but now it is open to everyone.
The big idea is letting people play how they want. You can team up and make a nation with rules and laws or you can travel thousands of blocks away and live alone.
There are rules but they are just the normal basic ones you would expect. The server also has basic commands like home back and tpa so getting around is easier.
If you have questions the owner says you can ask and they will try to respond.
