Meta has blocked over 544,000 accounts in Australia to comply with the country's new law banning social media access for under-16s, which took effect on December 10. The tech giant removed 331,000 Instagram, 173,000 Facebook, and 40,000 Threads accounts. Meta is urging Australia to reconsider the ban, arguing it could push teens to less regulated platforms and isolate them. The company advocates for industry-wide age verification and parental approval for app downloads as alternative safety measures.
