Blizzard has already 100% banned for use of TurboHud in the past, and there is a blue post about how it violates the rules.
I’m not going to invest the time in digging up the post since it was years ago, but it is there if someone cares enough to find it.
The assumption was TurboHud however it may have been something else too, we’ll never know the truth except the fact that was banned and admitted it.
