I can explain.
You are perm banned for griefing. You have now been banned twice for it. It's possible you do not realize this, but we log every block transaction on the server. It is never, ever okay to grief, steal or kill other players animals on Famcraft. I don't think this server is the right server for you. We take our rules very seriously.
I am sorry things did not work out here. I hope you find another server you will enjoy.
