Unsubscribe me

Holy crap batman. I subscribed by accident to a couple of forums. My profile now shows that I am not subscribed to any. I unsubscribed to all of them. Yet, I am getting every post from WordPress.org/support. I just reveived https://wordpress.org/support/topic/how-to-display-events-rather-than-posts/#post-8354405 at 12:21 pm.

How do I stop this madness?
