Good luck. Google doesn't disclose their algorithms. There doesn't appear to be any Google statement on this matter, either.
No, but for "honest" folks, they do provide guidelines : http://www.google.com/support/webmasters/bin/answer.py?answer=35769One can't really fault Google for taking the attitude "do it right, then spend your money on advertising (with us). If you do it half-ass and spend your money on SEO instead, we might smite you".
