Australia has implemented landmark social media restrictions for users under 16, which polls show are supported by ~80% of adults.
The policy has led to the removal of close to 5 million accounts across 10 platforms in its initial phase.
Snap (Snapchat) does not consider itself fully within the law's scope as a "messaging platform" but has complied, removing over 400,000 users aged 13-15 in Australia (~5% of its 8 million daily active users there).
Research on the impact of social media on youth mental health is described as mixed; a cited JAMA study found neither complete removal nor excessive use is healthy, with a "sweet spot" in between.
A key implementation challenge is enforcement: children are finding workarounds, and advocates like Paul Litherland are concerned about platforms' interpretation of "reasonable steps" to comply.
Ravi Iyer posits that global adoption of such age restrictions could reduce habit formation and network effects for social media platforms, dampening long-term growth and stock price performance, though companies would remain "wildly profitable."
Social media executives, like Snap's Jennifer Park Stout, argue for parental choice and nuanced approaches over "blanket bans," emphasizing built-in platform safety measures.
