This will only end when companies serving ads become responsible for their content. Yes, thorough verification of ads "doesn't scale", but cheap scaling is mainly a benefit to the company, not to the consumer.

I can imagine a major cable channel receiving heavy fines if they were to show an ad like that on TV. Why is it different with the ad giants?

It is funny that our society has the additional threat surface of a guy who really will give you $100,000 if you do This One Weird Trick

There's nothing good to be said about people scamming each other in every technological way possible. Other than that hopefully this gives us a new genre of cyberpunk where high tech and low life are achieved in a dog-eat-dog scammer-against-scammer world, rather than authoritarian oppresive corps. It could be quite cool to see this taken to its logical extreme in fiction.

They don't even filter regular scams.

I was even served malware on APNews.com (via Google Ads) awhile back...

But why would they work harder to filter them? That costs a lot of money.

We need image sensors that cryptographically sign their output so that images can be attested for authenticity.

This will get worse and worse the more the technology gets better and better. It will happen with news and cause mass chaos with false news stories to confuse people.

Would a public/private signature for videos work in solving such fakes? If not, why not?
