Yes. And it seemed to get more extreme after the Mayday update, too. From the areas that I track, May in particular was quite rough. Many mash-up sites (today's version of a scraper, IMO) were getting undeserved ranking boosts on lots of queries. However, that effect did get dialed back a bit in June and July.
