Hello there,
I made an account years ago and now going through all my old accounts and deleting the ones i do not use, I read that you do not delete accounts permanently but according to the new regulations that came into effect last month I have a right to be forgotten, so I could like my account and all my details to be permanently delete from your databases.
As someone has stated it would need a Sql query or owner to go into phpadmin and delete your details from the database but as you only have 1 post count i’m guessing you made a new account to post but give no mention of your old account details and I don’t think the owner is physic.
edit: Unless you’ve used the same email address which I don’t think you could do then he could search by that
