Interesting that he states they are making a note of any "good sites" that get falsely caught up. How can they tell "good sites" from "bad sites" if not by their algorithim?
It couldn't be a blacklist for known "bad sites" or there wouldn't have been any mistakes to start with. Are going off Webmaster Tools reinclusion requests? Reports in the media? Internal reports filed by Google employees for friends?
