Just look at some of the top sites that Blekko has banned as being content farms
Blekko is a bad example. My website and my biggest competitor's website are leading sites in our niche with thousands of pages of unique content on a certain subject (no content farm, but usefull info on one subject). Both sites have very good rankings on Google and Bing. Both sites are banned by Blekko ...
And ... the best of all ... the first result in Blekko's SERPS for our most important keyword leads to a 404 Not Found page of a website with as good as no information about that subject.
