What Could a Social Media Ban Mean for Youth Activism? 

A few weeks ago, Kier Starmer announced plans for a sweeping, Australia-style ban on social media for under-16s, saying that  “Social media is making our children unhappy,” and “prevents activities that help a child develop into an adult.”

Social media isn’t just entertainment – it’s where young people organise

For parents who watch their teenagers disappear behind screens for hours, the policy is probably a real relief. The mental health worries are well-documented, backed up by plenty of research and hard to ignore. Campaigners have made their case powerfully.

However, with this new law planned for spring 2027, there’s a real risk it could also quiet young people’s political voices. In trying to shield teens from the worst corners of TikTok, Instagram, and X, leaders seem to overlook that these sites are now where young people gather, organise, share ideas and participate in civic life. If under-16s are kept out, we could end up with a generation that’s been silenced before they even get to vote.

If we only see social media as a source of addiction, bullying, and low self-esteem, we’re missing just how crucial it’s been for recent political movements. For Gen Z and Gen Alpha, much of the politics now happens online. Again and again, teenagers have used digital tools to challenge those in power. During the Black Lives Matter movement, teens turned to Instagram and TikTok to share stories of police brutality and organise support from their bedrooms.

The School Strikes for Climate, launched by Greta Thunberg, went global because millions of under-16s could organise online with just a hashtag. In the UK, the 2020 A-Level algorithm protests showed this power too, as British teenagers banded together online to get the government to reverse unfair exam results.

What gets lost when participation moves behind closed doors

Without these platforms, the networks that let young people work together could easily fall apart. The government might argue that apps like WhatsApp and Signal are still allowed, but those private messaging apps don’t go much beyond close friends. They’re missing the tools that help turn a local problem into a national cause. On WhatsApp, you can’t just connect with a teenager in another town or find new people who care about the same issues you do.

Around the world, young people have shown what’s possible

For years now, young people haven’t just relied on leaflets or physical meetings to organise. Of course, online activism alone is rarely enough to create lasting change. Real change happens when digital conversations translate into action in communities, schools and neighbourhoods. But social media has become an important starting point for many young people finding their voice. All over the world, digital tools have become a lifeline for youth who want to stand up to failing institutions.

Take Brazil’s 2015–2016 school occupations: high school students, many under 16, led protests against school closures and budget cuts. They didn’t depend on political parties or unions run by adults. Instead, they used Facebook and live-streaming to organise more than 200 school occupations, sharing police actions directly with the public and shaping the national conversation.

Or look at Chile’s Estallido Social in 2019: secondary school students used Instagram and X to organise mass fare evasions on the Santiago metro, kicking off a nationwide protest against inequality. With the UK’s planned ban, British teenagers facing big challenges, such as cuts to youth services, a failing education system, and climate issues, could find themselves less able to act than young people in other countries.

The real problem isn’t young people – it’s the platforms

Ultimately, a blanket ban is a quick political fix. Tech giants haven’t done enough to protect young people, and strong regulation is long overdue. There is no denying the huge detrimental effect social media has had on young people’s mental health, cognitive ability and sense of self-worth. Social media platforms such as TikTok, Instagram, YouTube and X have never put the safety and wellbeing of young people first.

Rather than doing the tough work of holding tech companies accountable and demanding safer, less addictive platforms, the government has simply decided to exclude young people from the digital world altogether.

At Rekindle, we see every day what happens when young people are trusted to explore ideas, question assumptions and take meaningful action in their communities. Whether those conversations begin online or face-to-face, what matters is that young people have opportunities to participate, be heard, and shape the world around them. 

By banning all under-16s from social media, the government has further isolated young people from the political debate. And as we have seen throughout history, an isolated, silent youth is a huge loss for any democracy.
