Isn't identifying real humans an unsolved problem? I'm not sure efforts to hide the truth that these domain are actually the most requested domains does anyone any favors. Is there something using these rankings as an authoritative list or are they just vanity metrics similar to the Alexa Top Site rankings of yore? If they are authoritative, then Cloudflare defining "trusted" is going to be problematic as I would expect them to hide that logic to avoid gaming.
