It might help if the reasoning behind the request is explained. I can't remember a setting that allows someone to delete their account. (which I find highly suspicious to include on sites anyways. I have seen lots of sites that allow it also allow you to pay for content with that account that is only accessible by it. Nintendo is the oddest one. As deleting a account will delete all associated games from the systems that use that account. They do have a process to recover the lost games though and are willing to implement it when needed.)
Why isn't just not using the account not a solution?
The account was aparently made in oct 2014... at least that's what it tells me.
An account that old with only 2 posts.
One a request for deletion the other a bump.
