Actually, to give more detail, the bits about checking what you don't want to be emailed about really don't apply to what you get emailed about for forum notifications and digests. What you need to do is this:

After you go to Notifications, click on subscriptions. If you are subscribed to firionavie, then you are getting those spam emails about what is going on for this forum. Unsubscribe. You don't need to be subscribed to be a membver of firionavie Once you unsubscribe you'll stop getting those emails.
