This is a semi anarchy style SMP called DIH SMP.
Stuff is not really peaceful here and players can basically do what they want. It is not full anarchy but it is close so you have to watch your back.
All the info about how it works and what you should know is on their discord. You join there first and then you can get on the server.
If you like survival with chaos and not many rules this server is made for that.
