It depends on what they are investigating. For instance….you could have 1000000 hours played but if you decided to hack/cheat even once, then that’s enough to be bannable. Or, if you are accused of playing with a hacker but only played 1-2 games with them, then you are more likely to just get restricted instead of banned (but if you played an extended period with them and/or it was clearly known they were hacking, then that’s more likely to lead to a ban).
