All I want is a feature to black list certain domain names from search results. Similar to YouTube never show this channel again option. If google hosted such a feature then they would get a very strong signal on poor results and would go a long way to punishing bad behavior and cleaning up the net. It’s so easy to do that I have to assume they chose not to because they make a percentage of the revenue from the content farms.

I'm trying that now. But previously I was using the uBlackList Firefox extension with some block list subscriptions. https://github.com/rjaus/awesome-ublacklist
