the point is KYC don't help any of these bad things to stop happening since people can just buy fake documents and find a way to fake KYC (even paying someone else to do it for them)
what it does is create a parallel market that incentives fraud
I do not think that having "minors" here is the responsibility of Roobet at all. Of course they should make it go away, and they would prefer if there are zero minors here, that would be great. But they could fill the form in a fake manner and continue, not like they are not capable of doing it.
Another thing in the world where it is illegal for people under 18 to watch, but we all know people who are under 18 watches those things online right? They even get asked if they are above 18 or not before they watch those things and they lie and say they are above 18 and still watch them. Same logic, say it's not allowed and you should be fine to be fair, if they lie, then it's their problem.
