I have a MIG Switch and a few pirated games, though I’m afraid it will ban my account, including games I’ve bought.
I don’t use Switch anymore due to philosophical reasons, so it’s probably not a huge deal, but it would probably still piss me off, because I spent some money there.
Do you think it could be mitigated by resetting the switch to the factory settings and never logging in?
If you don’t want to risk getting a ban at all, the only safe thing is to not connect to the internet at all. Maybe there is some level of safety, but it could take only one mistake.
If we assume that we fully understand how nintendo catches this, we would still only ubderstand at that point in time. They could still change or push updates which could cause you a problem.
