Scores of children have been saved from abuse after an elaborate sting by Queensland Police led to the identification and arrest of key members of a global online sex abuse network. Queensland's anti-paedophile taskforce Argos targeted an internet bulletin board which had 45,000 members. Users were ranked according to the volume and originality of the child exploitation material they uploaded to the site. The site, the name of which remains suppressed by the South Australian District Court, was administered by ... Adelaide childcare worker Shannon McCoole. This month, the Families SA employee was sentenced to 35 years in jail for sexually abusing at least seven children in his care and for transmitting child pornography on the internet. McCoole's victims were in state care, and were as young as 18 months old. With McCoole in custody, Queensland's Taskforce Argos then activated phase two of the operation. Phase two was to take over the network," Detective Inspector Jon Rouse said. "Ultimately, you had a child sex offender network that was being administered by police." Two officers from Taskforce Argos secretly assumed the online identity of Shannon McCoole, working around the clock for 10 months to dismantle the paedophile ring and identify abusers. Detective Inspector Rouse said the sting resulted in the identification of paedophiles around the world. "US, Europe, United Kingdom. [It was] global," he said.
