I mean, it’s not beyond the realm of possibility that aimbotters would want to stay in bronze. They can be no different than the 6-stack smurfs that throw and just want to spend time killing “bronzies” for “fun.” Just use aimbot to kill a bunch of bronze people, and for a few games just turn it off and throw games to stay in bronze.
Also with how many sales of OW keep popping up, they don’t need to worry about people reporting them because they have 5-10 accounts waiting to be used.
