Ex-staff at outsourcing company Samasource claim they vetted unspeakably graphic videos in harsh conditions

• More than 140 Kenya Facebook moderators sue after diagnoses of severe PTSD
• ‘The work damaged me’: ex-Facebook moderators describe effect of horrific content

Smashing bricks against the side of your house is not a normal way to wind down after work. Nor is biting your own arm or being scared to go to sleep. But that was the reality for one of the 144 people diagnosed with severe post-traumatic stress disorder after moderating horrific content for Facebook.

The young mother in her 20s did the job in Nairobi for more than two years during which she claims she had to vet unspeakably graphic videos. These included extreme sexual deviancy and bestiality, child abuse, torture, dismemberment and murder, which caused her to vomit, according to court filings. On one occasion she recalled having to watch a person having sex with a snake.
