Today i got banned for no reason by scriptadmin, i was going hard with a 34/0 killstreak with my barret and i am 100% sure i aint cheating kinda sad cause i loved ar51 servers.. is there any way to get unbanned?

Name ingame is 'HcG'

I just installed game yesterday for the first time in my life, searched for a servers.. found this one.. tried to join it and it said that I'm permanently banned.. what the hell just happened? My game is added on PunksBuster by the way..
