I've been using crowd-sourced tools like SponsorBlock and Return YouTube Dislike, and I really like them. So far they've resisted attack using some kind of consensus algorithm. I've also been using the search engine Kagi, which lets me downrank and even eliminate certain domains and sites which I believe to be low quality. I wonder if it's possible to marry these. If the majority of users dislike a domain, it gets downranked. Of course bot detection and perhaps the use of logins might be required, but compromises must be made if the desire is a better search engine.
