I was aware of that, and it's exactly backwards. Google is punishing sites for having low-quality sites point to them (even if they have no control of them). What I'm suggesting is the opposite, that a site be punished for its outward links, if they point to low-quality sites.

(One could do this separately for various kinds of undesirable content and let the users choose whether they want to avoid spam, hate speech, plagiarized content, nsfw content, misinformation, Rick Astley videos, and so on.)
