Governments around the world are making efforts to crack down on teen social media use amid mounting evidence of potential harms, but critics argue blanket bans are an ineffective quick fix.

Australia became the first country to enforce a sweeping social media ban for under-16s in December, requiring platforms like Meta’s Instagram, ByteDance’s TikTok, Alphabet’s YouTube, Elon Musk’s X, and Reddit to implement age verification measures or face penalties.

Several European countries are now looking to follow Australia’s lead, with the U.K., Spain, France, and Austria drafting their own proposals. Although a national ban in the U.S. looks unlikely, state-level legislation is underway.

It comes after Meta, the parent company of Facebook, Instagram and Threads, faced two separate defeats in trials related to child safety and social media harms in March.

A Santa Fe jury found Meta misled users about child safety on its apps. The next day, a Los Angeles jury ruled that Meta and YouTube designed platform features that contributed to a plaintiff’s mental health harms.
