AskNebula.com Automatically Subscribed Me Without Permission

I received an email notification from AskNebula.com, even though I never created an account or signed up for any membership. It seems the website automatically subscribed me without my consent. I immediately canceled the subscription, but I want to make it clear that I never made any request or applied for a membership.

If any issue arises related to this so-called subscription, I do not accept any responsibility because I did not initiate or approve it. The fact that I was automatically subscribed without permission is unacceptable and raises serious privacy concerns.

I expect AskNebula to confirm the cancellation, ensure no charges are made, and remove my email address from their system permanently.
