Well, today I started doing my monthly ranking checks and I discovered in the past 30 days I have lost position on DOZENS of keyphrases. A quick check of the sites who have usurped mine reveal egregious foreign scraper sites using MY images and nonsense text ranking (same site) in the #2 and #3 positions. Mine is at #5. I quickly filed a DMCA to have the pages removed, but I feel like this is just the tip of the iceberg. I feel like no matter what I do, Google's apparent incompetence will guarantee we fail no matter what we do to be good web citizens and provide quality content.
Google's QUALITY detector DOES NOT WORK. I'm sure all of you can agree with that. This is ridiculous and infuriating.
