Black Hat SEO and Google

If you've done much research on search engine optimization, you've run across Black Hat SEO.
They have always been the looked down upon section of SEO.
But now Google seems to be lending respectability to Black Hat.
How?
Well a search for "Blackhat SEO" on Google gives you only 267,000 hits.
But if you look over in the right hand column, there are Blackhat SEO ads in Adsense.
"black hat seo" gives you 569,000 and yes, even more ads in the right hand column.
Ads like "Blackhat SEO Traffic", "Great Black hat seo Tool", "Black Hat SEO Secrets" and more.
Now search volumes are still pretty low on Google, the highest term being "black hat seo" at around 2,900 hits a month. And the terms are not very well paying.
But the idea that Google, that hates Black Hat so much, is running ads for it kinda amazes me.
