You mean buy used consoles or the game itself?
I suppose that an innocent person who brought the console and game brand new can also get into this mess?considering Nintendo is using a ###.XXX.XXX (the Xs meaning numbers that follow the first set of #) set code for both console and game which they ban things based on that string of codes, I would say yes. It's a reason I never use IP banning, because if anyone gets unlucky to get into that range of IP addresses, then they just end up banned.
