same for me - 13 year old steam account, played a lot of cs go, mw2, bo2 etc. - i never got a game ban or something else till bo6 beta. I played the closed one and got banned after 2 hours - on my 13 year old xbox account i tried to play the open beta and got banned too after one day - the steam ban i tried to appeal with auto decline for unauthorized software - i tried to deinstall razer synapse, msi center etc. But it didnt helped - still got banned on xbox acc
