Maybe I am missing your point, but I was mostly referring to what
Count Morado was indicating.
I do apologize if I am misunderstanding anything.
I don't believe you can have age verification without ID verification. People using Death Stranding as verification has already proven that to be a big failure. Norman Reedus has probably been ID'd to go on way too many adult sites by now, and that is kind of funny. He's pretty the most porn addicted man in the world at this point.
But to my point about zero trust, I think people will find that the needle of what is considered adult content is going to move swiftly once a standard is set. It will additionally not be able to be about moral opinion. Some form standard will be required.
I also see this returning to any M or higher rated game. You need to ID yourself to purchase it. And then we circle back to the "How do we effectively ID" argument, and then we return to the in person with government issued ID and a zero trust society.
Im not entirely sure how you can start slicing this pie apart without ultimately getting to the point where online purchases have to stop, except maybe for food or needed items.
My point is that verification is a very slippery slope and once people no longer trust each other it will go into areas you didn't think it would very very quickly, because that is how society operates. Regulations will take over for moral opinions and those regulations will have requirements that need to be evaluated against every product.
If you somehow believe this will be a situation that only applies to porny games, I have some lakefront property on the moon to sell you.
Im also unsure how you are referring to ilegal content. I would assume that my local crack dealer is not going to accept mastercard for my purchase and that MC would try to ensure that is blocked, regardless of ID verification.
