I bought a few of those games, everything worked well and the codes worked for me. I bought them because the seller had great reviews at the time and I thought that I was getting a great deal so everything looked good to me. but I noticed that over the last two days that the seller had 2 negative feedback about how their Nintendo account were suddenly banned for using fraudulent codes.
Now I’m scared that my Nintendo account might get banned out of the blue for this. Is there anyway to prevent this? I had no idea stuff like this was even possible. And why is this even a thing? I already gave this seller a positive rating so I can’t get my money back, like is there anything I can do at this point?
