P.S. One other quick thing. I saw you sending me tweets, but the tweets looked fairly repetitive, and you hadn't chosen a Twitter avatar. I get a lot of tweets from bots, and this looked fairly close to bot-like to me: https://twitter.com/mattcutts/status/315232934040846337/phot... That (plus the fact that the site had no current manual webspam actions, plus the fact that I wasn't sure what you meant by citations) meant that I didn't reply. Hope that helps.
Makes sense. All the tweets were by hand. I tried to tweet every weekday but missed some, then eventually gave up.
I just didn't know what to do upon getting no feedback from you guys after posting to the Google Webmaster forums, filing reconsideration requests, contacting friends at Google, posting to and commenting on Reddit about it, commenting on HN about it, posting to Facebook, blogging, and tweeting about it, and putting a yellow box at the top of all pages on the site mentioning the penalty and linking to a page with the details.
