Edit: No they do not.
It requires a system where the user:
(1) provide digital identification; or (2) comply with a commercial age verification system that verifies age using: (A) government-issued identification; or (B) a commercially reasonable method that relies on public or private transactional data to verify the age of an individual.
Unclear to me what the transactional data means, and if a charging a credit card would suffice, but it does not require 2 forms of photo ID.
The only major form of photo ID is a state/driver's license and passports and I think only 30% of the US has Passorts. It's such a big country that you can reasonably never require it and still travel more than the average EU citizen.
You can also fill out a form with your employer to get a photo form of employee authorization, but you're Sol of you're freelance/gig economy.
Not saying you’re wrong (I certainly don’t have any data to the contrary), but this isn’t intuitive to me. Don’t tons of people send their credit card (which is linked to their SSN) to PornHub? From there seems like a small step to also send ID?
Most Pornhub users aren’t paying ones, or even logged in at all. It’s all there publicly, unless you want to leave a comment or whatnot.
Few things are truly impossible or 100% correct. There's not much value in arguing such extremes.
