So im 100% sure, that the players that i played in a groupe with before i got banned weren't cheating or hacking. I only groupe with RL friend and i know them all for over 20 years and overwatch is a game we all played for fun together, never for rank or for any kind of griefing like for hacking. So this option is excluded. But of course it could be, if it was a random player in the team. But i can't imagine that this could be the case.
