“Police state.” That’s the framing I keep seeing around banning under-16s from social media. It’s backwards.
Australia’s ban took effect in December 2025, the first of its kind, and the loudest objection is that age checks mean mass surveillance and a government ID database. But the law explicitly bars platforms from forcing you to hand over a government ID to prove your age. The state is not building a record of who you are.
The part nobody wants to sit with: the data already exists. As Australia’s eSafety Commissioner pointed out, platforms don’t really need to “verify” who’s under 16, because they already know. They have spent a decade building targeting systems precise enough to flag a 14-year-old from behaviour alone. The surveillance machine wasn’t built by the government. It was built by the platforms, and it is aimed at children.
We know what it gets used for, because it is in the court record now, from unsealed documents and sworn testimony. A former senior Meta policy executive testified that the company flagged teens by emotional state. A girl deletes a selfie, that signal gets read as her feeling bad about her appearance, and it becomes a moment to serve her beauty and weight-loss ads. Internally, 13 to 17 year olds were described as a “vulnerable but very valuable” demographic. Meta’s own research found Instagram made body image worse for 1 in 3 teen girls.
So the real question was never whether the data exists. It does. The question is who gets to use it, and on whom. Right now the answer is advertisers, on kids.
You can argue about whether a ban is the right tool. You cannot pretend the surveillance is hypothetical. It is the business model.
