Topic: Can you delete a nintendo network ID?

@SuperWiiU: My account is 1 week old, so is my console. For that week i've downloaded a LOT of demos... Only a day ago i realised about all this mess. And all of this JUNK is connected to me forever. I just don't want them to be related to me in any way.
You can't understand this kind of pain. I'm being paranoid because of that.

Well, you can always replace your Mii character, you don't have to change the actual NNID. The Mii is the only thing that is publicly viewable in most cases.

I think I missed the point at first, sorry.

So you don't want your account to be connected to certain demos in any way, huh? Well, I would advise against deleting your ID for that reason. However, if it really kills you, and you don't have any downloads or DLC, than you shouldn't really have anything to fear. It will unlink the account from your 3DS AND Wii U, and all of your Miiverse data will be deleted, I believe it will also delete any DLC that you might have.

But just keep In mind, it WILL Delete data off of both your Wii U, AND 3DS, if you have them both linked to the same NNID.

The choice is up to you. I can empathize with you to a certain degree, I tend to get paranoid about similar things as well. Also, if you don't mind me asking, what is it that you want to be so disconnected from? I can't think of any "adult" rated software on the Nintendo eshop right off hand...

@Bat-Moves98: I wanted to disconnect my account from all that 40 demos, which are listed in my games list with no reason. There were no embarrasing, strange or disgusting games at all, it's just a... PRESENCE of these games, games, which i will never play again and will not be interested at them, that's what making me so uncomfortable.
Well, i did format my 3ds and all that demos have gone from games list... However, they're still in history of purchases of eShop. Well, pretty enough for me, i guess. Atleast eShop doesn't show me that i "bought" those demos previously, that would be a catastrophy.

@aacprime:

So you just don't like the fact that you downloaded all of the those demos?

In case you were worried, the history of having downloaded all of those demos will not take up any extra space or data on your system, its just there as a reference in case you are ever curious which games you bought, or so that the Nintendo customer service can have proof of what you bought, in case of some sort of technical mishap that would cause you to lose your games etc.

Personally, I almost never go to my download history, so I have never had an issue such as yours, but everyone has their own quirks and I can respect that. If you want my advice, just try to forget about it. You certainly didn't do anything "wrong" or "shameful", so there is no need to get so stressed.

I was once banned from Miiverse, and I felt very similar to you. I ended up being unbanned after waiting a week, but I couldn't help but feel ashamed that I had gotten myself banned. Needless to say, I have learned my lesson. (Although I must admit that some of the rules in the "code of conduct" are a bit silly, and too restrictive. I mentioned a mod for Smash Bros melee and got banned)
