Teens, Social Media and Mental Health: Age Laws and Evidence — 2026-09-25
This week: the EU's Kids Act gains momentum with bans under 13 and "mini accounts" for teens, while Meta's multibillion-dollar US settlement moves into implementation as states prepare to receive billions. Australia's under-16 ban faces a High Court challenge backed by US tech, and researchers warn the world still lacks methods to measure whether bans actually help teens. TikTok dropped its appeal against a record UK fine for failing to keep under-13s off the platform.

EU Kids Act: under-13 ban, "mini accounts" for teens
The EU Kids Act presented by Commission President Ursula von der Leyen would bar children under 13 from social media across the bloc, allow supervised "mini accounts" for 13–15-year-olds, and impose "safe by design" requirements banning addictive features (per Euronews). Korean commentary notes the EU is going beyond content filtering to regulating the design structures that keep teens glued to screens — an approach where Korean legislation is moving more slowly.
Australia's HCA ban fights back — in court
Anthony Albanese has been touting Australia's under-16 social media ban abroad, but Big Tech companies and the Electronic Frontier Foundation are backing Reddit's High Court challenge to strike down the world-leading law (Politico, Sept 21). The outcome will shape the legal risk profile of under-16 bans and age-verification laws elsewhere, including the UK, which is set to follow.
Researchers question whether bans work at all
A STAT News opinion (Sept 22) argues that with Australia's ban live and the UK following, the research community must "meet the moment" with new tools to measure whether bans improve teen mental health. The Genetic Literacy Project (Sept 25) goes further, reporting that Australia's ban has so far produced "more workarounds than results" — exactly why rigorous evaluation is needed. These critiques matter directly for legislators weighing under-16 bans.
States set to receive billions from social media settlements
As Meta's multibillion-dollar settlements begin paying out, states are deciding how to use the funds for youth mental health programs — but reporting notes "the case is far from closed," with ongoing distribution and litigation questions. The settlement, worth roughly $18bn, includes teen safeguards such as night-time use blocks and daily usage limits on Instagram and Facebook.
TikTok drops appeal of £12.7m UK fine for under-13s
TikTok (Sept 24) abandoned its appeal against the UK watchdog's £12.7m fine from 2023 for failing to enforce its minimum age limit and remove underage users — an enforcement signal for age-assurance obligations in the UK.
Local view
South Korea: Gyeonggi education chief An Min-seok urged the National Assembly on Sept 19 to legislate youth SNS age limits and platform accountability. Seoul Shinmun reports (Sept 24) that the Broadcasting & Media Communications Committee is deliberating 8 pending bills on youth SNS overuse, weighing measures from under-14 sign-up bans to parental consent and recommendation-algorithm restrictions. Segye Ilbo (Sept 23) frames the global spread of under-16 bans as "lights out, Instagram off" while flagging free-expression and privacy concerns — approximately 40 countries now restrict by age, with effectiveness in doubt.
France: Le Petit Journal explains the Kids Act for European readers, noting von der Leyen's text follows France's own contested under-15 ban, which was censored by the Conseil constitutionnel and is being reworked via a new bill submitted to Brussels.
Context & numbers
- Meta settlement value: up to ~$18bn, with teen protections including daily two-hour limits and no visible reactions on posts for under-18 users (CNBC, Al Jazeera; Aug 2026).
- 40+ countries now impose age-based social media restrictions; ~70% of South Koreans support limiting teen SNS use (Korea Press Foundation survey, Aug 14–19, 1,000 respondents, reported by Media Today).
- UK fine TikTok stopped fighting: £12.7m.
- As of August 2026, at least 21 US states have enacted laws on minors' social media access or addictive feeds (AVPA tracker).
On the radar
- Reddit's High Court challenge in Australia — a ruling could undercut precedent for under-16 bans globally; watch for hearing schedules.
- UC Berkeley's California "alpha phone" — rumor stage: Korea's Democratic Party plans a student-only smartphone task force with Seoul public consultation from late October, targeting launch decisions by mid-2027.
- California's AB 1709 (restricting social media for teens) — teens are being engaged on the bill via KALW's teen-produced program; track committee progress.
- Age-estimation tech scrutiny: regulators doubt "age inference" ML systems are fit for purpose; expect Ofcom/ICO follow-up guidance on what counts as "highly effective" age assurance.
