Account can't be deleted. i can give you a suggestion if you do that you will lost your account permanently And you can't bring her back even if you want to

- Since there is no email confirmation required to create an account or change email in the forum, you can go into your profile and set a wrong email that is not under your control.

- Then set a long password with special symbols that is not possible for you to memorize that. and do not note this password anywhere

- And finally delete the private key of the bitcoin address used in your account account

Now just log out the account then forget about the account as after that you will not be able to access that account anymore.
