I don't wish to discredit this. But in my niche I have 4 sites on many keyword SERP ahead of me (after Panda) that have those full page/ throw the content to the background ads that pop up when you visit any of their pages.

I find it hard to believe that my quality score gets affected for a stray adsense unit when all of those sites SE traffic doubled after Panda.
