Gaming

Short: I opened up the Nintendo eshop on a hacked 2DS. And didn't realize my brothers main Nintendo account was logged in, as I usually only play offline. Will his account get banned?

Long Question:

I recently hacked my 2DS with https://3ds.hacks.guide/ and installed pirated games on it. And I was curious what would happen if I open the Nintendo eshop, it opened up and to my surprised showed an account and the purchased game. But I never had logged in with an account before.

I quickly realized this is from my brothers account, when I gave him the 2DS a few years ago. He logged in with his main account. It is not possible to remove the account from the 3DS operating system unless a factory reset is done. And that's bad, because this account has a lot of history for him, his Pokemon history and everything that is attached to him. I do not want his account to be banned. My fear is, that a ban wave will occur later.

After reading a bit, I found out that the NNID can be removed with the hacked system. I hope its not too late. Would it be possible for him to reclaim his account in case of a ban?
