I read through the entire list of sites reporting in on the WebMaster Tools thread. Yes, there were a number of MFAs, but what really stood out to me was all the 10 year old sites that got slammed. One guy even had PR=8 for the homepage.
I don't have a great critical design eye, but some of the serious content sites (the basket mine fall into) looked awfully good to me. Many of them commented on getting ripped-off all the time and suggested duplicate content issues.
And yes, I would have given them my credit card AND followed their medical advice.
