Facebook under fire over child porn A Facebook spokesman said: Unfortunately, these disgusting individuals exist in our society and, on rare occasions, on Facebook. However, no service has done more to seek them out, remove their content, and help bring them to justice than Facebook. We have a zero tolerance policy for child exploitation materials on the site and take industry-leading measures to try to accomplish that goal including building a dedicated team of professional investigators, integrating Photo DNA, a technology that scans all images on Facebook and flags know child exploitative material, developing a collaborative partnership with NCMEC and law enforcement specializing in child protection, and building many cases that have been escalated to law enforcement. The average amount of time indecent content stays on Facebook is three days. In March earlier this year, The Telegraph revealed that Facebook's outsourced moderation process shares more personal information with third party moderators than it has so far acknowledged. The social network was criticized earlier this year after gossip site Gawker exposed it as employing third-party content moderators in the developing world for one dollar an hour. Facebook responded saying: "No user information beyond the content in question and the source of the report is shared." However, new evidence seen by The Telegraph in March, showed that these moderators, who have to deal with the distressing images and messages which are reported every day, and are clearly able to see the names of the person who uploaded the "offensive" content, the subject of the image or person tagged in a photo - in addition to the person who has reported the content. Moreover, there are no security measures in place stopping these moderators taking screen shots of people's personal photos, videos and posts. When challenged about the data displayed on the screenshots shown to The Telegraph by an ex-Facebook moderator, a spokesman for the social network said at the time: "On Facebook, the picture alone is not the content. In evaluating potential violations of our rules it is necessary to consider who was tagged and by whom, and well as additional content such as comments...Everything displayed is to give content reviewers the necessary information to make the right, accurate decision.
