First, thank you for approaching us and appologizing.
If you are the same person that I banned, please confirm your steam id, then what happened is that you ran out of the saferoom prior to anyone else on the team being ready. You triggered the tank and were immediately killed. Then you logged off. Myself and other players were asking you to get back to the saferoom, but when you logged off, it appeared that you were attempting to grief the server. By griefing, I mean that you intentionally were trying to play poorly to make the survivors lose.
When you confirm your steam id, I can lift the ban.
However, please be aware of the server rules. What you should have done is not rush out of the saferoom before everyone is ready. Stick with the team and help them. If you go to far ahead of your team, you could be banned again.
