How do I remove myself from all forum subscriptions?

I am receiving email notifications of all posts to the EOS 3.0 bug reporting forum and other even though I have set all my email notifications and subscriptions to 'off' or 'unsubscribed' in "Manage email subscriptions" and notifications settings. I even tried changing my email in myETC and I am still receiving emails. I tried classifying ETC emails into my junk mailbox but they still come through. At this point, I just want to delete my account if I cannot resolve this. Please help!
