I don't know any good reasons of why i should be allowed to play on the server
If you can really change for the better, and get rid of the trollish and childish behavior then that would be a pretty good reason. Question is, are you capable of doing that? You haven't convinced me yet.
given the chance i would still fuck it up.
If you really believe that, then why are you here requesting to be unbanned? Chances are not just given, they are earnt. You've wasted far too many already, and it's because of your "idgaf i will still fuck up anyway" attitude.
