This server is called 1fighter2defenders or 1f2d and it is a wild survival world. It has no rules at all and the map never resets so everything people do stays there.
People can grief builds and also build huge bases. Players are allowed to cheat and basically everything is allowed. It feels like pure chaos and you never really know what will happen next.
The server started in 2021 so the world is already really old and thousands of players have joined at least once. You can use Minecraft version 1.21 as the main one and it also supports versions from 1.17 up to 1.21.11.
If you want a place where nothing is protected and you just try to survive against the world and other players this is that kind of server.
