It does make me wonder if Adsense placement isn't at least part of the scoring.
Part, for sure, but only a part. if the first thing gbot finds on a majority of your pages is an adsense block, not good. if gbot finds adsense on a majority of your pages, not good.
add in affiliate links, bad inbound link pattern, considerable inbound links from content farms, questionable outbound links, thin content pages, doorway pages, blah blah blah... toast and probably should be.
