In case this helps anyone else using Adsense/Blogger, I received a message about a week ago that my site would be delisted from Adsense because the layout (probably unchanged since 2007) had an unacceptably misleading layout (nonspecified) (and inexplicable). I requested a reconsideration, and was informed today that after further thorough review, the matter was resolved and the site is in compliance.
(My genuine thanks to Google for keeping Blogger so dependable all these years)
