Despite you breaking a the RDM rule as crossfire is no excuse for RDM I can see how this can easily be a mistake especially when raiding a base in a heavily populated area. The main reason for your ban was that you also had other recent punishments but I see you received a ban for that already and then immediately got re banned for breaking 1 rule which is not all that fair in my opinion. I suggest that in future you watch what you are doing and cut down on your rule breaks.
Let me make it clear to you that the admin was not at fault in anyway I just feel they were too harsh in this situation which is of course just a matter of opinion.
You will be unbanned,
