"Everyone must prove their age online now" creates a trail of identity that kills anonymous speech dead. Anonymous speech is very important to maintaining freedoms... such as freedom of speech and freedom of association.

Yes, this is one of those game theory traps like the prisoners dilemma, because it requires coordinated action across a large group of people. Unfortunately the lowest common denominator parenting is not able to handle the problem, because the parents don't understand the situation, are addicted to platforms themselves, and just generally don't have the necessary skills.

Government regulation is a ham fisted approach that risks unintended consequences / secondary effects, but it is generally good at breaking the game theory traps because it changes the playing field for everyone. That is fundamentally why we have government at all - to solve coordination problems.

>not a fan of the government approach of "everyone must prove their age online now", which I believe is how the AU law is done

This is not how the law is implemented. The vast majority of verification is being done by 'age inference', ie analysis of the content the user consumes or posts to infer likely age. Only accounts suspected to be children by the inference process are being required to verify or have the account disabled. In practice, the inference process means very few accounts are required to provide any proof of age. Personally, I haven't been asked to verify by even a single website.

The age inference process is described on this page under 'What is Age Assurance?' https://www.oaic.gov.au/privacy/your-privacy-rights/social-m...

If you think we can't depend on parents for the kids education, school should handle it.
