we need some sort of a universal crowd-sourced site rating system. Things like user experience, scamminess, user-hostility, site ownership-affiliations,etc.. all opt-in by users of course, you setup the criteria that is important to you and the browser displays different ratings or blocks certain sites (like scammy/fraudulent ones) out right. The reputation providers would also be selectable like search engines. I'd imagine there would be crowdsourced lists of all sorts.

If you have older pepople struggling with cognition for example, this would be a good way to limit their exposure to scams.

But commercial sites like this could also be rated as a privacy risk for the intense ad capitalism, or a 'bloat' to tell users it will slow down their computer by visiting the site. You could set it up so that when certain categories and ratings are met, the browser warns you before you could navigate to it.

Another idea is to have this same system include alternative suggestions. For example, if a site has age verification, you would be able to setup your browser so that it warns you when you visit sites of that nature, listing alternatives recommended by the list maintainer, for whatever that site provides.
