The proposal consists in filtering out crappy or scoring sites based on how much affiliate links and ads they use. In addition, it could also penalize:

  * GDPR popups
  * excessive JavaScript
  * presence of modal dialogs requesting email

It's an idea I've been thinking about since a long time. It should also include filtering out "scraping" websites which republish content from other websites (like pinterest) and websites which make block content behind pay- or login-walls (like again pinterest).
