I found 99b99t and it is a brand new Java anarchy server where anything goes. There are no rules and no limits so players can do whatever they want.
The world is fresh so it feels like everyone is racing to survive and take control. It runs on Hard difficulty so fights and mistakes hit harder.
The server is up 24 7 and it supports Java versions from 1.12.2 to 1.21.11. If you want pure chaos and survival this is that kind of place.
