My guess is that they ran into trouble because of the small amount of text on the average page, and/or the extent to which the same topic is discussed on numerous other sites.
I think you're unto something, Bahamas.com has a vendor section which is short on info. The same day this hit I removed my 'tags' section, that had more thin pages than the rest of the site. It was removed by the Webmastercentral on 2/25 so I am hoping.
