For years, “stranger danger” has shaped how parents talk to children about online safety. UNICEF’s largest-ever study of the issue indicates that understanding may be badly outdated. Most children who are sexually exploited online are targeted not by strangers, but by people they already know, on the same handful of mainstream apps that their parents assume are safe, shows the study. The report, published on September 3, 2026, estimates that roughly 20 million internet-using children across 21 countries were affected in a single year, and that the true global toll almost certainly runs into the tens of millions.
Disturbing numbers
Titled Through Children’s Eyes: How Digital Technologies Enable Child Sexual Abuse, the study draws on two rounds of UNICEF’s Disrupting Harm research: surveys of roughly 21,000 internet-using children aged 12 to 17, gathered between 2020 and 2025 across Africa, Asia, Latin America and Eastern Europe, alongside in-depth interviews with 100 young survivors. The work was carried out under the Disrupting Harm project, run jointly by UNICEF, ECPAT International and INTERPOL.
Of the children affected, an estimated 15 million were exposed to unwanted sexual content, nine million were pressured into sexual conversations or asked to share sexual images, and four million had intimate images shared without their consent, according to Deutsche Welle’s summary of the findings. Separately, Reuters reported that across nine of the countries surveyed, an estimated 1.1 million children said AI-generated sexual images or videos had been made of them – a sign of how quickly the threat is evolving even as the underlying data stretches back several years.
Lasting scars
The report’s starkest contribution may be its data on long-term psychological harm. Children subjected to online exploitation were found to be roughly four times more likely to report suicidal thoughts, self-harming behaviour and markedly higher anxiety levels than their peers, according to a media release from UNICEF Australia.
UNICEF Executive Director Catherine Russell said that these experiences cause profound emotional and mental distress, and many children suffer in silence, unsure where to turn. That reluctance shows up starkly as 41 per cent of affected children told no one about what happened to them, and fewer than one per cent of cases were ever reported to police, a social worker or a helpline. The report’s authors described the pattern as insidious rather than sudden, in which ordinary conversation gradually curdles into coercion and then entrapment.
The findings complicate the “stranger-danger” assumption that still dominates much child-safety messaging. Only 16 per cent of perpetrators were unknown to their victims; 57 per cent were people the children already knew – friends, family members or romantic partners – while the remaining 27 per cent said they could not identify who was behind the profile targeting them. In many cases, the report notes, online abuse was accompanied by abuse in person.
Platforms under fire
Nearly 60 per cent of reported abuse took place on mainstream social media – led by Meta’s Facebook, WhatsApp and Instagram, alongside Snapchat and TikTok – rather than on Meta’s platforms alone, as Reuters’ reporting on the launch makes clear. Online gaming platforms, which often carry built-in direct-messaging tools, accounted for a further 14 per cent of cases.
Meta responds
A Meta spokesperson defended the company by noting that the underlying survey data stretches back to 2020 – before the company rolled out several of the very safeguards UNICEF is now recommending, including defaulting teen accounts to private and blocking unconnected adults from messaging minors. The company also disputed UNICEF’s classification of WhatsApp, arguing it is a private messaging app rather than a social media platform, while saying it would continue to fight child exploitation aggressively across its apps. TikTok, for its part, told Reuters it has built safeguards including private-by-default accounts for under-18s and detection technology aimed at predatory behaviour.
The report has come just days after Meta agreed to pay up to $17.1 billion to settle US state lawsuits alleging its platforms harmed children – a settlement, announced on 26 August 2026, that also caps teen usage at two hours a day across Facebook and Instagram and blocks access overnight. The deal suggests Meta had further to go than it acknowledged, despite the company's insistence that it is proud of its child-safety record. Governments worldwide have already begun restricting the company’s platforms more broadly.
Global pushback
Australia became the first country to bar under-16s from major social media platforms, in December 2025; Indonesia introduced a similar restriction for under-16s in March 2026; the United Kingdom is set to follow, with its own under-16 ban due to take effect in spring 2027; and Germany is weighing a tiered model combining age limits with mandatory age verification. France's attempt at a similar law, setting the age floor at 15, was struck down by its Constitutional Council on free-expression and privacy grounds in August 2026, though Paris has said it intends to draft a narrower replacement.
For its part, UNICEF is urging a three-pronged response: safer-by-design platforms with stronger privacy protections for minors, tighter national laws that close loopholes exploited by offenders, and trustworthy reporting channels that make it easier – and less shameful – for children to come forward. As WeProtect Global Alliance executive director Ian Drennan put it, children’s safety must be non-negotiable.
The abuse documented in this report does not stand apart from the wider ecosystem of image-based sexual violence and pornography-driven harm that NWS reported recently, examining how a nearly $100 billion industry is reshaping a generation’s understanding of sex and consent.
