But it's affecting all types of sites, including one of a kind major corporate sites that are not showing duplicated or scraped results in Google.

I see it the most with ecom sites - original content or no. Like I said, weakly link, deeper pages with shallow content.

If the site does not rely heavily on long tail searches, there is no blip to the traffic, but if it does, the site loses big time on traffic. That is why I suspect a sub-supplemental index. It can affect traffic. If it was just a "broken" operator, this would not happen.

It also explains why WMT's count is different than the site: count. WMT shows a count of all indexed pages, site: would show only "viable" pages.
