I'm considering buying a second-hand New Nintendo 3DS, mainly to play Pokemon Sun/Moon which is a bit "heavy" for the old 3DS.
But there's a thing that restrains me. I've heard that players who downloaded pirated copies of Pokemon Sun/Moon are having their 3DS systems banned from all of Nintendo's online services:
As a result of a number of Nintendo 3DS users using unauthorized versions of several games, and connecting to the official game servers in violation of our terms of service, these users’ Nintendo 3DS systems that stored the unauthorized game code have been banned from Nintendo's online network effective immediately.
So, here's my question:
Is this ban tied to the user Nintendo Network ID or to the 3DS itself?
In the former case a format of the 3DS will solve the problem. But the latter is a big deal, I don't want to buy a not-specified-length-of-time banned 3DS, and I can't test them if they are sold online.
