How can I delete an unknown email?

Is there a way to delete an unknown email on my account?

 

Nope, there is not. All you can do is get the account locked and recover it back, entering whatever email you want it to be registered to. You can enter a new email in account management too, but you have to wait ~a week, and I'm guessing that's not what you want.

 

oh, so lock my account and when i recover it, i change it to whatever email than just take it off once i do that?

 

Yeah when you get the account locked, fill out the recovery appeal and at the bottom enter whatever email you want the account to be registered to. When the appeal gets accepted, submit your new password, and the new email will be set.

 

lock the account recover it back.

 

Not sure if this still works, try it:

Recover your account, and the e-mail will auto changes to yours.
