Or as a relevance measure. On the whole I think Google errs on the side of safety. They can do more to remove a lot of possible noise but then you end up throwing out way too much good stuff too. "smart" is as smart does. With a clean database it's already hard enough to return and rank *really* relevant data. With a tainted set like Google's... wow.

What if I was also to tell you these keywords were part of an seo contest. What if I was to tell you my page wasn't created until after the contest was over, with no active link building on my part (I get scraped to death). What if I was to tell you this page ranked for it's term until I mention it and some engineer comes along and killed it ... twice. Of course google should be "smart" enough to catch this but they aren't so what if I was to show a blog post where all of the text was a 4 word phrase repeated 10 times.
