For every site that has moved down there is a site that has moved up. The people who moved down always make the most noise those who move up want to remain off the radar screen.
Sometimes for 1000 sites that went down, Amazon, Wikipedia or Walmart went up in rank so it's not always one to one. When known brands are purposefully promoted, small sites get screwed.
Or for sites that went down, their scrapers and other spammers went up. There also many old sites that are no longer maintained that gained in rank and have taken the place of actively maintained small businesses.
