Surely Google follows their own guidelines: You can't find Google Search Engine results indexed on Google itself (or any other search engine with or without ads for that matter). Google Search is more of an application than a content site.

Otherwise, when Google finds itself breaking the "rules", they act:

- Google banned the page for Chrome for buying paid links

- Google banned an acquired company (Beatthatquote) for violating rules.

- Google penalized their Adwords FAQ pages for cloaking.

- Google reduced pagerank for Google Japan for buying links.

- Google removed Adwords support pages for keyword stuffing.

It's almost like Google is a massive corporation with different departments and contractors who don't always coordinate together.
