Australia said on Wednesday it will add YouTube to sites covered by its world-first ban on social media for teenagers, reversing an earlier decision to exempt the Alphabet-owned video-sharing site and potentially setting up a legal challenge.

YouTube is the latest website to be banned in Australia for kids and teens under the age of 18.

The Australian government has announced YouTube will be required to ensure account holders are at least 16 years old starting in December

Google is expanding its AI-powered age checks to more of its apps, and your search history could now get you flagged as a teen.

YouTube is done trusting the birthday you type in, so it’s now using AI to figure out if you’re a teen or an adult, then acting accordingly. Just a day later, Google said it’s taking that same approach and applying it across all US accounts to spot minors and apply the right restrictions.
