Youtube has problems lately. It has suddenly started to send me notification emails everyday non-stopped. The unsubscribe links had no effect. Even after I have unsubscribed a number of times, the spam kept coming. Finally I deleted my account but the spams kept coming in anyway. Of course marking the spamming emails as spam in GMail doesn't work. Worse there's no way to contact Youtube to report the problem.
