Hi, you can get banned on any gears of war game. If your not sure why you are banned then you will have to get in touch with Epis about this issue, Microsoft cannot offer you anything with this issue. You may have banned for glitching, modding, unfair play, cheats or you could been in a modded game without even knowing, that can happen. It happened all the time with modded lobbies in MW2/3. People into modding are just ruining games for everyone else, go mod a PC if you have to mod at all
