Earlier quoted context omitted.
Which is true. Irma/Yivi [1] in NL/BE proves that to be the case. But it always works with a trusted third party. The client, after confirming auth with the human, generates a unique key for the platform. The platform asks the trusted third party to verify this key, and then a scope is defined. For example: 'is this person 18+?' the response to the platform is then 'Yes' or 'No'. [1] https://yivi.app
So, the trusted third party gets to know which sites you visit?
All the platform gets to know a person 18+ is visiting their platform. In their data analysis, they could add such information to the rest of their data analysis such as IP, but this wouldn't be within scope (illegal in EU). Just worth it to mention in case a platform gets compromised.
So:
Username Bob, age 18+ (verified), from IPv4 1.2.3.4, visited PronHub, at 2 AM, with browser XYZ.
vs
Username Bob, from IPv4 1.2.3.4, visited PronHub, at 2 AM, with browser XYZ.
If Bob isn't logged in, they have to auth every time they visit.
And this is going to happen due to nefarious actors. LLMs (AI), as well as state actors in countries behind the other fence of Iron Curtsin in the New Cold War.
