You meant it has been recreated. But before recreation there is an amount of time when the account is not recreated. It is possible to remove an account by having a bot that tries to login periodically and deletes the account. Given that the period of the check is just a bit longer an adversary can effectively make the account unusable. You need to hardcode the check disallowing deletion or changing the password of the account with the name "cypherpunks". It's just 2 if in the right places!
