After getting beaten by me at a online game that person subscribed me to Warner Bros Enterntainment mails. For more than 1.5 years now, I've been getting emails that are impossible to get rid of. The unsubcribe link in the mail leads me to a web page that always has said "Error
Our systems are offline. Please try again shortly." Amazing, for more than 1.5 years, that function has been non-functioning.

And every email I've tried to send to them has either just disappeared or bounced back.
