GabbanaCraft is a Minecraft server where the main focus is anarchy pvp and survival. It is made to work with all 1.xx.x versions so it is easy to join.
From what I can see the world is meant for players who like wild fights and risky survival. There is no hint of strict rules so it feels like you can pretty much do what you want and see what happens.
Right now the server is still growing. They plan to reveal the server ip when they hit 20 players. On December 17th there were 8 players already so it looks like a small but growing community.
