> Self-declaration, the "I am over 18" checkbox, is explicitly prohibited by every major regulator in the UK, EU, and Australia.
But then:
> Facial scanning works, but it builds infrastructure that outlasts the check. A system that estimates your age today can identify you tomorrow. Platforms that rolled it out met immediate backlash and reversals. Users do not trust platforms with their face.
How would we trust your platform to not store voice fingerprints, then?
(On a side note, all descriptions all LLM-written, but that's expected in 2026)
