It's analogous to the credit card fraud problem, no? E.g. disputing charges and chargebacks?
I don't work in that space, but my understanding is that the card processors essentially serve as dispute mediators in those instances.
So it would seem unavoidable (although not great) to have some sort of trusted, third-party middle person between collectors and end users, who can handle disputes and vouch for consent.
Blockchain doesn't seem like a solution, given that the problem is precisely in the digital-physical gap. E.g. I have proof of consent (digital) but no way to tie it to a (disputed) act of consent (physical).
