I've been uncertain exactly where these products have been originating from, some seem to come from template driven affiliate sites--others have a much more original feel to them. The end result, unfortnately, is that it doesn't really matter if the products come from an affiliate type source, the MLM company that is distrubuting the catalog where the majority of these products are found, or a manufacturer who is offering them also. The problem lies in that there are so many of them out there that the content is not original and therefore cannot be listed in the ODP.
I personally have seen at least 200 sites selling some combination of these same products in the last month (and I am unfortunately not even exagerating) and they are coming in every day in pretty high numbers.
To be listed a site must offer original content. It would not be fair to list your site, when there are huge numbers of sites selling those same products who are also being denied. It doesn't have anything to do with the actual quality fo the products, but the sheer number of sites offering them. Sorry <img src="/images/icons/frown.gif" alt="" />
