Honestly, focusing on AI seems silly since the internet, at this point, is completely neck-deep in deceptive scams being pushed by reputable, mainstream, important orgs.
Google, Facebook, Amazon, etc. take in literal billions of revenue to show people scam ads. The scammers are directly paying them money - presumably these are not anonymous orgs, but people with credit card numbers and ID. And the big internet giants just gladly act as for-profit middle-men for ripping off confused elderly people, because reviewing the ads posted to their platform isn't practical.
Something has completely failed in enforcement.
