That's exactly what I thought.
If the bans are permanent, in about 2 months I plan to call Nintendo and say I bought a used system and my online doesn't work. I know I deserved getting banned, but in this country I have to work almost an entire month to even get the money required to buy another N3DS, add in rent and bills and I'll pretty much have to work 3-4 months for one. That's not possible when I have so many other important shit to buy. This was a straight kick in the balls, especially since I only went online Sunday night to Monday morning.
