The error page on nintendo website seems to be restored to the old access point issue.

while the users were banned, it was :

"if you continue" suggests that they are working on fixing the issue and you had to tell them if you still had it.


It's now back to

Though, some users displayed two console connected to the same access point, one being banned and one working online, confirming that it wasn't an access point issue.


Edit:
The error page seems .. to change after each refresh!
is it a cache bug?

 

It's possible it was only a random issue and it took them two weeks to fix.

One user said the representative person he called confirmed it as a ban because of the use of unauthorized material, and that nothing will be done to be unban.
The nintendo error page mention "if you continue to experience it", meaning it shouldn't happen.
Nintendo doesn't have a "banned console error code" page. If nintendo want to ban someone, it will have a proper ban code and description.

There's no proof it was a ban, except that user who called nintendo (I don't remember who did it, it's in the linked thread).


to me, if it was really a ban, we would had a looot more reports.
20 user is a strange number for a "ban-wave" considering the number of Sky3DS users.


I compiled what we know and what we don't here :

Edit:
I edited the title to be more accurate, as it's maybe not a ban and even less "unban".
