Coming on the forums and acting like a child will not get you very far in this community
i suggest you grow up and learn how to be respectful towards other people
Welcome to the community!
You could have been banned for a number of things boosting, going afk, using glitches in the map, stuff like that
The only thing you can do is wait for the ban to be lifted which is anywhere from 24 hours to 2 weeks
My best story would have to be when i was playing war games i stuck a pretty beat up warthog with a sticky getting a triple kill, as i started to walk alway i get a double splatter as the warthog slamed into two people after i blew it up
best lol ever
