How Australian police hosted a pedophile forum on the dark web, which had thousands of active users, in order to execute a global sting operation

Context & Ripple Effects
This sting did not come out of nowhere: US court documents had already shown Australian authorities hacking Tor users inside the United States and sharing findings with the FBI a year earlier, so running the Childs Play forum itself is an escalation from surveilling dark web users to operating the platform they gather on.
The Guardian's reporting on the forum — with thousands of active users — sits at the center of a short arc that runs through Norwegian hacker Einar Otto Stangvik's later exposure of how Childs Play was hosted, and points forward to the same Australian-FBI pairing running the AN0M encrypted chat service for over three years: the tactic scales from a forum to full criminal communications infrastructure.
First-order effects
- Thousands of active forum users become identifiable to Australian police and their international partners, converting a community that believed itself anonymous into a global suspect pool.
- The FBI gains a ready-made stream of evidence and leads from a platform it did not have to build, at no cost of running its own honeypot.
Second-order effects
- Independent researchers like Stangvik are forced into the role of external check: when police host illegal content, disclosure depends on outsiders rather than oversight bodies, putting agency secrecy and researcher transparency on a collision course.
- Other agencies see the model validated and move up the stack — the AFP and FBI's later AN0M operation shows the shift from hosting a forum to supplying criminals' everyday encrypted messaging.
Third-order effects
- If law enforcement routinely operates the infrastructure of criminal communities, the legal questions multiply across borders — the earlier Tor hacking already showed Australian actions reaching US users — pressing courts and legislatures to define when hosting a crime becomes committing one.
- Dark web trust dynamics structurally change: users must price in the possibility that any forum or service is state-run, pushing criminal activity toward smaller, harder-to-infiltrate channels.
The trend: Law enforcement is moving from infiltrating criminal networks to owning and operating their infrastructure, with Australia and the FBI as the recurring pair.
