So my brother likes to be a little shit and hack cause it "funny" he says till I come home and want to play on a bf4bd server which was flubber and it said in the chat ban for multi hack I immediately knew it was him because he likes to get on without my permission so now I have to lock my  computer up in a fucking safe way cause he will figure out a way to get in and play on my account so I was wondering if it was possible at all to get a unban if not that sucks but if so thanks
