OAIC has provided guidance on the privacy obligations for teen socmed ban age checks. They're much clearer and more detailed than anything eSafety has provided, once again demonstrating that OAIC is a place filled with serious grownups doing real work, not children playing dressups like some other agencies I could mention.
I note that the privacy requirements are pretty onerous, which in some ways is good. But it shows that people are right that small, low-risk platforms are disproportionately affected by this kind of blanket "no teens allowed" ban, like we said all along, despite the mendacious protestations of certain proponents of this nonsense.
