Google's site, How Search Works, features a prominent Fighting Spam section which features live spam takedowns and some other interesting details. For example, here is some gambling spam that Google has removed from their search results.

Within the Fighting Spam portion of Google's latest resource are statistics showing:

• Manual takedowns
• Type of spam taken down
• Website notifications via Webmaster Tools
• Reconsideration requests

Here is a screenshot of spam manually removed by Google, and the varying categories of spam.
