Europe’s youth social media bans are coming — and marketers must adapt

On Sunday, Czech prime minister Andrej Babiš said he backed banning social media for under-15s, citing advice from experts and framing the move as child protection. “I am in favour because the experts I know say that it is terribly harmful to children. We must protect our children,” he said, adding no further detail.

Babiš’s intervention would have sounded like an outlier a year ago. This week, it reads more like a marker on a fast-moving map. In the space of days, Slovenia said it was preparing draft legislation to ban social media access for children under 15, Greece said it was “very close” to announcing a similar ban, and Spain’s prime minister publicly set out an under-16 prohibition, folding it into a broader crackdown on what he described as a lawless digital space.

For marketers, this is not just another bout of regulation to be handled by legal teams and compliance checklists. It is a distribution shift that reaches into channel strategy, creator partnerships, first-party data, and measurement. If these policies stick — and if they are enforced through credible age assurance rather than self-declared birthdays — the practical effect will be fewer reachable teens on mainstream platforms in the markets that adopt bans, and more scrutiny on any activity that even appears to court underage audiences.

One important nuance is that governments are not presenting these moves as conventional “content regulation”. They are framing them as a boundary around access itself, often justified through mental health, bullying, and addiction concerns, and aimed at the mechanics of the platforms rather than the choices of individual children. That matters because access limits, if enforced, change what inventory exists, not merely how it is policed.

It also matters because this is not a uniform consensus story. Reuters reported that Jose Cesar Perales, a professor in experimental psychology at the University of Granada, said there was no unanimous agreement that social media harms adolescents. The debate, in other words, is moving forward politically even as the evidence base remains contested in places. Marketers should expect uneven rules and uneven enforcement, while planning for volatility across markets rather than a single global operating model.

Changes for marketing teams —

So what changes inside a marketing team when youth social access becomes a policy battleground?

It starts with a hard look at planning assumptions. In markets that impose under-15 or under-16 account bans, teams can no longer treat teen audiences on major social platforms as a dependable baseline, even for campaigns not explicitly aimed at young people. Long before enforcement bites, the reputational risk of appearing to target children rises, even for the grey zone of spillover from broad targeting that delivered younger impressions.

That shift also forces a more honest answer to an old question: who is the customer? In many categories, teenagers influence what is desirable, but parents or guardians control payment, permissions, and logistics. When teen accounts are restricted, the most scalable route to outcomes is often the household gatekeeper, supported by creative that acknowledges the family purchase dynamic without sounding preachy. The proof points change, too: safety, durability, educational benefit, total cost of ownership, and parental peace of mind take on greater weight when the purchaser is not the end-user.

Channel strategy follows. Even if youth reach on mainstream feeds contracts, “youth relevance” does not vanish. Brands that still need cultural proximity will look harder at entertainment partnerships, sport, gaming ecosystems, retail media, and creator work where audience controls are clearer and the talent is demonstrably adult. The goal is not to recreate teen social media elsewhere. It is to move from precision targeting to influence through context, community, and distribution partnerships that can withstand scrutiny.

As platforms tighten access, first-party data becomes more valuable, but also more dangerous to mishandle. Marketing teams will need cleaner age-gating on sign-ups, tighter rules for competitions and community features, and stricter suppression logic for “unknown age” users. In practice, the safest position is often to treat “unknown” as “do not market” until eligibility is established. That ensures a brand can credibly say it did not build growth by accidentally collecting minors.

Measurement, inevitably, becomes the next pressure point. If parts of the audience become inaccessible or less trackable, teams fall back on incrementality tests and mix modelling, then use retail and search signals as proxies for teen-driven demand.

Reuters reported that Snapchat, commenting on Australia’s approach, argued that a ban “leaves significant gaps that could undermine its goals,” including limits in age-verification technology and the possibility that users shift to unregulated messaging apps. Those gaps may complicate public policy. They will certainly complicate attribution.

Babiš’s statement in Prague, Slovenia’s drafting work, Greece’s near-term signal, and Spain’s high-profile proposal are all part of the same emerging reality: governments are no longer content to ask social media platforms to be safer. They are increasingly willing to redraw who can participate at all. In that environment, marketing strategies must be adaptable and resilient, embracing channel mixes that do not depend on teen social reach, data practices that can withstand scrutiny, and creative strategies built for households, not just individuals.
