Historically what we do in the States is put the onus on whoever is placing the ads to make sure that their disclaimers and disclosure obligations are fulfilled. It seems to me, though, that we could take advantage of the vaunted machine learning AI capabilities of these platforms. If the machines can detect that the name on the ad bears no relation at all to the source of the payment, you would think they could have a human being take a look at it and say, “Hey, let's just make sure we have the right name here on the ad.”
It's not the way our laws work right now, though.
