Back on my old Wii I use to get banned for hacking. This stop me from playing any games online. But there was a homebrew app to change my serial number and other numbers to unban myself. Where there be an app like that for Wii U? Thought there should be a topic on this
Well, you deserve it. It is better to obey the rules rather than break the rules. That's simple. You should know better. I never got myself banned because I won't do that and I obey the rules since Wii and now PS3 for years.
