Most people want to operate within the boundaries of their society.
A simple G/PG/PG-13/R header for websites would solve 97% of actual issues anyone could care to present. (violence, porn, etc)
Forcing people to identify themselves will not solve skinner boxes, gambling-for-children, focus-degrading slop, etc.
Bluey-themed slot machines are still harmful.
Do… you think kids are accidentally finding porn, thinking it’s for them, and partaking? Why would any teen see a “mature” rating on a website and go elsewhere? This is the kind of response I expect a literal alien from another planet to make.
As an aside, why would a mature rating on a bluey themed gambling machine change anything? I may have a unique perspective on this because I worked at blockbuster for a decade but I PROMISE you parents largely do not care. If you want to solve the problem, hoping parents solve it isn’t… actually a solution of any kind.
