This is where Google is actually hurt by the long tail world of millions of small sites. It's easy to evaluate the top 100 or 1000 web sites to make sure they're reasonably legit. It's much harder to monitor 1,000,000 blogs to make sure that none of them were machine generated for the purpose of scamming AdSense revenue. Still, I don't think Google has a choice: I predict that you'll see a massive expulsion of smaller AdSense sites by Google, and it better happen soon, or AdSense will ruin Google's reputation among advertisers, something which could be deadly.
