It began with a tipoff.
While reporting on trafficking and the exploitation of migrant workers in the Gulf, the Guardian journalist behind the investigation was contacted by a source known for more than a decade. The message was alarming: child sexual abuse trafficking in the US was increasing, and as the Covid pandemic pushed predators further online, some were using Facebook and Instagram to buy and sell children.
The year was 2021. At that point, the company now known as Meta had not yet rebranded and was still operating as Facebook. There had been little public reporting on the role its platforms were playing in this abuse. That gap helped set the stage for an investigation that would later become part of a legal fight against the company.
The journalist teamed up with Mei-Ling McNamara, a human rights journalist, to examine what was happening online and how the trafficking network functioned. The work involved speaking with experts from anti-trafficking nonprofit organisations as well as an American law enforcement official, who helped explain the crimes they were seeing and the patterns that had emerged on social media platforms.
The resulting reporting uncovered evidence that would later be used in a case against Meta. In March this year, the company lost a multimillion-pound court battle over its failure to prevent children from being sold on its platforms.
The investigation is a reminder of how a single source can lead to a wider inquiry with major consequences. What started as one warning about online child exploitation developed into a detailed examination of how predators were using Facebook and Instagram, and into reporting that helped expose the scale of the abuse.
It also highlighted the broader shift in trafficking and exploitation during the pandemic, when more activity moved into digital spaces and the internet became a tool for arranging and hiding criminal transactions. According to the source who first raised the alarm, that shift was already being exploited by those looking to trade in children.
The Guardian’s investigation, launched at a time when there was little reporting on these abuses on Meta’s platforms, became part of a much larger reckoning over what companies knew, what they failed to stop, and how vulnerable children were left exposed.
For the reporters involved, the story began with a simple but urgent warning. What followed was a long investigation into a hidden network of exploitation, and a legal outcome that brought new attention to Meta’s responsibilities and failures.
