Known paedophiles are using Facebook to swap explicit images of child pornography, according to a new investigation by the BBC. The closed group settings on the social network mean that groups remain invisible to most users, but an investigation by the UK broadcaster found a series of groups being created and maintained for men with a ‘sexual interest in children’. The groups – which are named with a clear indication to the content and images – are reportedly being run by convicted sex offenders who are currently signed to the UK sex offenders register. Images were taken from newspapers, blogs, clothing catalogues, as well as photographs taken secretly in public places. Videos of a child’s dance show was included in one of the group’s pages. As part of the investigation, the BBC created a number of fake profiles to gain access to the groups – which they then recorded and documented users, images, and sexually explicit comments to report to Facebook. Despite the nature of the content, the BBC report that just four images of the 20 reported were removed by Facebook for breaching community standards. Speaking to the BBC, a spokesperson for Facebook’s public policy department said that the social network is committed to removing "content that shouldn't be there". Facebook says it removes content that includes "solicitation of sexual material, any sexual content involving minors, threats to share intimate images and offers of sexual services". Following their investigation, the BBC has reported the images, groups and usernames to police, the Internet Watch Foundation and the National Crime Agency.
