Who would cause the disabling of Google network partner sites

I would love to access to the data as to which blogs have been removed from Google's nework, how long they have been with Google and what exactly merited their removal. Certainly, such information would not be made available by Google, but wouldn't it be interesting to look into this data to find if there were similar root causes for a number of cases. I would love to see proof in the data that claims that perhaps someone else is causing accounts to be shut down. For example see this latest post on the subject and comments relating to it (http://www.websitebabble.com/adsense-other-ad-serving-programs/1477-banned-click-fraud.html).
