Michael Fluckiger has been sentenced to 20 years in jail for running a site that trafficked images of child sex abuse.
The site, called Playpen, was located on the Tor network used to anonymise web-browsing activity.
Fluckiger helped Playpen members see and read “tens of thousands” of messages relating to the sexual abuse of children.
He managed membership lists, enforced site rules and deleted any content that was not related to indecent images of children.
Playpen was located on a server on the well-known Tor network which hides the identity and location of browsers by encrypting data and bouncing it between different computers.
Law enforcement agencies caught the site administrators, and many members of Playpen, by using techniques that stripped them of the anonymity Tor can provide.
