@true - I'll second your hypothesis...a few years ago I thought it would be a good idea to "enhance" our blog content with store feeds from SAS, CJ and LS. There is a datafeed plugin out there that dripped XML datafeeds in posts at about 2 per day. That ran for 2 years, but affiliate sales were minimal. All in all we had about 3000 pages of this trash, many pointed to out of stock items and most posts receiving no more than 40 to 50 hits each. After the Jan 26th drop, I dumped all those pages, generated a new sitemap and now we wait. I'll admit it, to me that would constitute a type of thin duplicate content, but it was on my blog, not my main site. No mater, my new policy is "no data feeds whatsoever". That's kinda sad, because they were good , related products. If it was paying, that would be another story, but it doesn't.
