Aha! Maybe that's it. Must be that Google knows this too and is banning from Google all sites showing adsense ads and having low conversion numbers in order to boost the conversion for Adwords advertisers. i.e. Increase the ratio of Yahoo/MSN referrals to an adsense publisher and increase the overal conversion for adsense ads :-).
