I did not unsubscribe someone unsubscribed me?
Then your account is in control of someone else - possible your
parents if you are a minor child. Or, if an ISP determined that
someone was using their resources unlawfully, they could also
terminate your service.
If talking about eMail, then congratulations. Finally, we get
automatically unsubscribed for something we never subscribed to in
the first place. Hate having to "opt out" of crap when I never
"opted in" in the first place.
