I was banned from halo 3 matchmaking this Sunday. I was boosting in Grifball and out of 3 people I was the only one banned. (Go figure) So now i am wondering, is it possible to unban myself from matchmaking? I don't think it is possible because it's my console that is banned not the account. I could go on my friends xbox and play just fine. Thats just a fact that i know.
