No, the Brave browser does not try to verify that the page that it's replacing ads on has opted into Brave's "rewards" thing. They'll s/page_ads/brave_ads/ and collect a check regardless of if that revenue is going to the page owner or not.

My point was that this literally does not happen. Brave does not insert ads into pages, ever, it only removes them. I'll admit I'm skeptical of the whole cryto-currency model, too, but I try to keep my points factually accurate.
The only connection is that your browsing activity determines how much each content provider is owed.
Stop spreading FUD.
In my opinion this is also the ideal system since it removes the fundamental problem of advertising. And that is that when a company relies on advertising, their customer is no longer the people visiting their site - but the advertisers they make money from. This can lead to advertiser influence slowly creeping into every aspect of the site, including the content that is created. By directing the ad revenue to the user who then directs it to sites (at their discretion) it keeps the benefits of "free" sites, while removing all the nastiness that generally comes with ad-based revenue systems by untangling the relationship between advertiser and content creator.
