Brinked in every case the only ones that outrank us are cheaters violating the wmgl to worst. I'm not paid links, I'm talking doorway pages, redirects, duplicate sites using different keywords. Google doesn't read spam reports. You are wasting your time.
Whatever changed is coincidental. They didn't demote the eyeglass criminal after thousands of spam reports. It took a ny times article.
The same goes for products like merchant where huge adword spenders are the only ones getting away with cheating. It will take the next article for google to say "gee golly we don't know how this one advertiser got away with murder."
Bing is going to win this battle not because they were better. They will win e e rising because they didn't soak up the extra 40% of the web that was mostly garbage. The minute google flipped the switch on caffeine is the moment this all went to heck.
