Australia will enforce one of the world's strictest social media laws starting December 10, banning users under 16 from opening accounts on platforms like Facebook, Instagram, TikTok, and Twitch.Platforms must verify user ages with measures such as government ID or biometric recognition, or face fines up to 49.5 million Australian dollars.Meta has started closing under-16 accounts ahead of the ban while Twitch, owned by Amazon, was added due to its interactive livestreaming content encouraging social interaction among minors.
