i dont know u can try emailing them to delete ur account

You can't delete the account yourself, you gotta send a contact form requesting the devs to delete your account.

It was previously asked by other people. Account removal is not possible, but perma banning it is. Just tell them for a "safety reason" or anything of that sort.

Thank you.
