Misc I got banned for no reason?

[ItsJohnny]

Hi, I've been playing CTGP for a while now because my wii's wifi card stopped working, so I bought a ethernet to usb adapter that works fine. After I installed this, I wanted to play Mario Kart online to play the new KO mode. It might be the new adapter that got me banned, so if that's the case then I can guarantee that I'm not going to be cheating with it nor would I know how to cheat. (and if I do somehow cheat then you can ban me permanently again and not unban me) Thank you Wiim and Lesserate for considering my unban.

Oh actually i see what might have happened. After i system formatted my wii, i downloaded a mkwii save from the internet to unlock everything and that might be what happened. If that's the case, then i hope you'll understand.
Thank you!
