On Kagi you can increase/decrease a domain's ranking for your personal search results, and they make the aggregated stats public, showing for example Pinterest as the most blocked site, which matches part of what you're looking for: https://kagi.com/stats?stat=insights

I hope whoever is running Pinterest sees they are the top 7 most blocked sites.

...and that whoever is running HN sees that they are the #5 raised, and #5 pinned site.

I'm hoping/dreaming it would be browser-standard, as a protocol. Kagi would be one of the reputation providers in that scheme.

Funny to see w3schools.com ranking above Twitter.
