We need an addon to exclude content-farms from search results

Aren't you fed up lately with all the noise you get when searching for something? I mean, people do have the right to express freely, but when I search for something, I'd like to limit the results to types of sites like Wikipedia, Goodreads, Medium, but exclude all the Wordpress, blogging platforms, anything that a kid,can setup, because the've read somewhere that if they write content for words people search, they'll get rich. Lets separate the natural from the monetization greed. We have an AdBlock list. We need a FarmBlock list.

I forgot to say, they want to write content not because they have something to say but because thet want to target the first result on your first search page.
