Maybe it was reactivated by compromise? I would reset your password, review the access history, and delete it again.
The problem is, I don't have access to the email used to create this account. I created this account long time back, when hotmail was a thing. I haven't logged into that email account since 2004. I tried getting access to it, but wasn't able to do so. So basically, this account is in a weird state where it exists, but I don't have access to it.
Sounds like your email was compromised
