Isn't the UK legislation for _strong_ age verification? Selecting your date of birth from a dropdown is not strong age verification. Under age people do know how to pick something that make them seem older. I think that age selector is usually there for adult games when you are not logged in (regardless of the country). I never really see it, bc I log in before I use itch.
I think this is a red herring. The uk stuff has people sent pictures or use their ID and stuff tonprove they are of age.
