You raise a good point. E-mail spam is mostly fixed, and, if I remember correctly, a relatively easy solution works good enough: ask users to mark spam as spam and e-mails that look similar[1] to spam would be banned. Which got me thinking: surely that would work for websites too? Why not let people report low quality of sites directly to the search engine? Kagi lets you to ban sites you find unhelpful, but it doesn't downgrade websites similar to the one you've banned. I shan't speak of Google practices as we all know them by now.
