How about uBlock Origin, but for search? A crowd-sourced + manually vetted ban list at the domain level. Google is too timid and can't just permaban low quality SEO spam domains for fear of getting sued, instead they can only tweak the algorithm. But a community solution has no such limits. Copying Stack Overflow questions and answers to your site? Entire domain is banned, no appeal process, nobody using "uBlock Origin for Search" will ever see your site again. Boom, done. Maybe it could be done as an extension? It puts a little ban button next to a search result on google.com, that instantly bans the domain locally for you, and also nominates the site for the global ban list. I feel like there's a lot of low hanging fruit here, like completely banning just the top 1000 SEO sites would already dramatically improve the results.
