I found a full anarchy server where everything is allowed and there are no rules at all. It is made for players who want total freedom and do not want the server telling them what to do.
It runs from 1.7 to 1.21.11 so a lot of different versions can get in. There are no anti cheat plugins so it is truly anything goes.
It also supports Bedrock players using Geyser so both Java and Bedrock can join. It is on a free host with a subdomain but it has performance plugins and it starts up automatically when you join.
