Direct IP: anarchy.mc.kiwifarms.net
This is an Anarchy server. The only rules are: don't be annoying, don't cheat. Anything else is fair game.
Your spawn point is a large protected island and its surrounding water. The kits provided at the stalls (right click the signs) give you various ways to depart the island.
Be aware, Mojang loves doxing small children. If you have an old Minecraft account, visit https://mcuuid.net/ and see if your ID or your ID history compromises you. If it does, either don't play, buy a new account, or don't tell people if you post on Kiwi Farms. This is an open server.
I'll add more details as people complain.
