Many countries are still weighing ways to reduce social media's negative impact on children. The largest test case so far — Australia's under-16 social media ban — has now run six months, and the results do not point where supporters hoped.
What six months in Australia showed
The latest status report from Australia's eSafety Commission lands on three findings.
- Most teens circumvented the ban.
- Platforms failed to enact adequate restriction measures.
- Most importantly, there was no demonstrable effect on the wellbeing of young users or on behaviors associated with problematic online use.
The third finding is the one that matters. The stated purpose of the policy has not produced measurable evidence of success. Worse, bans may push teens toward less safe corners of the internet rather than off their phones and into the real world.
Where the regulatory push originated
The current wave traces to a 2021 Wall Street Journal report based on leaked internal Meta documents, alleging the company's own research found Instagram harmful to teenage girls and that Meta prioritized usage time and profit over acting on it.
The report triggered a major U.S. investigation, and in 2024 Mark Zuckerberg appeared before a Senate online child safety hearing, where he apologized to parents of teens harmed on Instagram. Analysis from social psychologist Jonathan Haidt further amplified concerns about teen mental health.
Meta has responded that most accusations oversimplify the process and that mental health professionals are divided on the effects of social media. The company is currently fighting a wave of mental-health lawsuits, arguing that social media addiction is not a recognized medical condition and therefore cannot ground liability. If addiction is recognized as diagnosable, exposure could run to billions in compensatory claims.
The advertising consequence
Regulation is already reshaping media plans. Per eMarketer, brands are planning to cut digital ad spend in response to any U.K. teen ban. In France, the push for teen restrictions faces a significant legal challenge centered on freedom of expression for younger users, according to Reuters.

The alternatives on the table
1. Parameters instead of prohibition
New Mexico Chief District Court Judge Bryan Biedscheid ordered Meta to pay $567 million and laid out a multi-step approach the company must implement in the state.
- Make all profiles of users under 18 private by default, and block adult users from connecting with teens by default (Meta already does this)
- Eliminate push notifications for under-18 users from 10 p.m. to 7 a.m. daily, and 8 a.m. to 3 p.m. during the school year
- Hide like counts by default for under-18 users
- Enforce a 90-hour monthly usage cap across Facebook and Instagram for under-18 users
This puts parameters around usage rather than cutting access entirely.
2. Moving age checks to the app stores
Meta continues to argue app stores are a better arbitrator of user age, holding more control in the access chain and reducing inconsistency between per-platform approaches while providing a stronger age signal from store profiles.
3. Digital ID verification
Under discussion in the EU: a digital ID requirement for all social media users, including teens, tightening access restrictions at the identity layer.
What marketers should take from this
- "Conditions" are more likely to land than "bans." Time-of-day restrictions, notification blackouts and usage caps change when and how often teens are reachable. Campaign scheduling is directly affected.
- Age-verification infrastructure may move. If it shifts to app stores or digital ID, the accuracy and availability of platform-level age targeting changes with it.
- Regulatory risk is budget risk. As the U.K. case shows, brands cut spend ahead of enforcement, not after.
