I have been "currently restricted from Miiverse" after inserting the name of my YouTube channel in my Miiverse biography. After seeing the notification for the first time, I removed anything having to do with YouTube from the biography. Weeks after changing the bio, I still get the message and I can't post anything. I am thinking about contacting someone at Nintendo, but before I do that I was wondering if anyone on the forums would know anything.
Please reply as soon as possible.
Oh, and my Miiverse name is Randomkiden if that will help anyone.
