You've been drinking the Google kool-aid. Google has always been the primary financier of web spam on the Internet. They knowingly profit from Adsense on spam sites. If they wanted to, they could end web-spam over night by banning Adsense accounts for spamming.

SEO is just another form of marketing. It is no more/less legitimate than PPC campaigns. In fact, PPC ads are far worse because Google does little to police them. As long as Google makes money, they don't care if you scam users. That's why they paid half a billion dollars in a settlement to the FTC for knowingly selling illegal pharmaceutical ads.

Like it is that simple. There are millions of adsense accounts. You can't hand pick everyone. Penguin 2.0 was supposed to hurt spam sites and judging by the fuss it created in Blackhat SEO sites it succeeded a lot.

They hand pick spam sites and remove them every day... There is an entire department dedicated to detecting spam.

They're pretty tough on spam, actually; far more strict than any other network I've dealt with.

They will manually remove sites for spam in their own search engine, but they don't ban the associated Adsense account. In other words, they are more than happy to pay you to spam other search engines.

One of my AdSense accounts was just banned (testing cloaked traffic to made-for-adsense sites), so I beg to differ.
