How to get rid of other accounts except this one

I forgot the password because I haven't been here in years. I even forgot the email I used so I just created a new account. Then I was locked out for multiple accounts. I forgot how to delete an account.

I don’t think you can if you forgot your account password and email. Welcome back though! It’s been ages since I’ve seen your user name!

Thanks! It has been ages, indeed.
