Thanks for your answer, and sorry for my late thoughts... I understand your position, and surely there would be many challenges, but if publishers adopted this proposed API, Google's results would be fairer and, potentially, their crawling could become more efficient (unnecessary?). Clearly they would carry the burden of providing a way to report malicious registration... but again, the moment badguy.example.com claims to host original content and it receives 20+ complaints... it's game over for that domain!

With regard to the notion of a private company controlling copyright issues, I'm a first believer that Google, big as it is, is not the Internet. An honest effort to clean up their index should not be confused with an attempt to censor anything. Taking the flip side: prove (via a simple API) that your content is indeed original, and then you'll be welcome in our index. Needless to say, only a dominant industry leader could take such a bold attitude.
