There are browser extensions for blacklisting domains from your Google searches. I've been so incredibly happy using one if them. If I see one of those despicable content farms I just blacklist it and move on. Often when I search on Google for technical stuff I only get 2 visible results on the first page, 1 SO and 1 documentation. Soooo relaxing.
The business reasons why Google doesn't take steps to remove the bad content and make their product pleasant to use again is so far from my understanding it might well be aliens running the company for all I know.
