When going through the setup for creating an account ont he website instead of the 3ds itself, you set a password to log into. Unfortunately, there's no 16 character limit like there is on the actual console, so you can make an account that you cannot edit, cannot change the password, and cannot log into the console as you can't type in the initial password you created.
#Possible to create an unusable account via the website which can't be used on console

I'd upload this to the forum, but I tried to delete my PNID to recreate and fix said issue... Which resulted in me not being able to use my username lol
well, you could just used reset password option
