I just received the email:Hello,
Blogger Terms of Service: http://blogger.com/terms.g
Blogger Content Policy: http://blogger.com/go/contentpolicy
-The Blogger Team
This happened almost immediately after I added HTML script recommended to me from AdBrite.
Use of the dashboard review request will generally repeat the originally offered verdict.
Review of various discussions in Webmaster Central indicate that AdBrite is not well regarded, in anti malware circles. One helper there suggested that AdBrite has a problem with security, allowing spammers to publish into their service - which puts unacceptable content on the blogs showing their ads.
If you want to publish a Blogger blog which does not get periodically locked as a suspected spam host, you might want to consider using a different ad hosting service - and to remove any similar third party gadgets from your blog.
