Can you give any specifics? Unless I'm too stupid to figure it out, mathematically, the only possible way to do that is simply ignoring (potentially) spammy links, instead of considering them negatively. I mean, SEO linkfarm --> publisher site looks the same as Competitor's linkfarm --> publisher site.

For most of your comments are getting greyed out, I might think that there is some other people that'd back my words.

You're Google employee, right? You lot have gone quite cheeky nowadays. You're exploiting the monopoly you hold in the search market, to make people adhere to your standards, instead of adhering the standards the internet community naturally generates. I'd suggest Google engineers to go develop better algorithms instead of telling the internet off.
