More than 140 Facebook content moderators have been diagnosed with severe post-traumatic stress disorder caused by exposure to graphic social media content including murders, suicides, child sexual abuse and terrorism.

The moderators worked eight- to 10-hour days at a facility in Kenya for a company contracted by the social media firm and were found to have PTSD, generalised anxiety disorder (GAD) and major depressive disorder (MDD), by Dr Ian Kanyanya, the head of mental health services at Kenyatta National hospital in Nairobi.
