Looks like you have everything off already. Including admin emails, which you didn't need to turn off.
On subscriptions, what you turned off prevents new subscriptions. I'd have to guess you have old subscriptions still around. You can delete them from your UserCP, but it might be involved if you've had autosubscribe on for a really long time.
I've wiped all your subscriptions. Let me know if you get any more unwanted emails.
