[flagged]
I literally cannot remember the last time I had to show proof of age to buy tobacco or alcohol. I'm middle aged - mid 40s, in fact - and places don't ask. If I order alcohol, the reason I'm showing ID is to prove that yes, it was me that ordered it instead of someone else (and I'm showing my ID at the liquor store). I've only bought porn twice - once a video and once a magazine full of naked men. I didn't get carded…
Your appearance is the age verification. One can obviously tell you are of age to buy the products in question by looking at you. That’s the age verification.
Communities are permitted to determine what constitutes age appropriate materials and at what age those materials can be consumed. Such standards ought to apply to web content too. There is nothing special about online that indicates it should be exempt.
