Consumers like you are the reason they can get away with literal theft. When they have people like you who blindly trust their authority and judgement without any burden of proof, they can do anything they want. And yenno what? There’s nothing that’ll change your mind, because people like you (the steam forums have THOUSANDS) have knee-jerk reactions to cheating accusations.
For the record, I can still play MW19 and WZ1 on the banned account, and I can play MW2 Open weekends and WZ2/DMZ on a new (F2P) account on the same PC, with the same software and background programs, with the same motherboard and hardware. Their anti-cheat is broken as fuck.
