If that's the username you had when you were "banned" It doesn't say you were banned.. you've just not logged on for 3 months. However if you do join again, please don't hack and use Xray! And you can carry on playing.
Very well, you've been unbanned but you were banned for breaking our rules, so if you do it again. You're gone for good.
We're not gonna forgot about you, It's only been 11 days since your ban, the last temp ban we had was a month so you have a while more to go. In this time I suggest you build something on single player and blow it up, get it all out your system.
