How To Save Your Blog From Spammers!
Directions (on how to save your blog from spammers):
1) Log in to your blog
2) Select SETTINGS (from the tab choices at the top)
3) Choose "Email and Mobile"
4) Scroll down until you see "Posting Options"
5) Change your custom email address to something the spammers will never guess
6) Consider making all emailed material arrive in "draft" form so you can review before it is published
Voila!
Funny that it took me a week to figure this thing out (and couldn't find it addressed in the blogger forums either!)
