It does make me wonder if Adsense placement isn't at least part of the scoring.
I've wondered that myself. How to test though
Maybe. I have a small (200 pages) site that's been online for three years, one that I haven't worked on in at least a year. It gets very light traffic, is in a very competitive niche, and has Adsense skyscrapers on the right side of every page next to the text. It wasn't hit at all. Don't know if the AdSense not blocking the page text had something to do with it, or if the site was too small to bother with.
If any site deserved to get hit, this one did.
