The rise in generative AI technology has made scamming people online much easier, with fake versions of Tom Hanks, Mr. Beast, and other celebrities often appearing in online ads. YouTube still has a problem with fraudulent advertisements, as I've learned from my own YouTube feed over the past few months.
Yeah it doesn’t block YouTube ads, because YouTube hosts the ads locally. No reason to have the ad provider host their own, when YT already has the infrastructure built to host them. Trying to use DNS to block YT ads would also block the videos themselves, which sort of defeats the entire purpose of using the site.
