A former Facebook content moderator filed suit against the company Friday, alleging that her job gave her post-traumatic stress disorder (PTSD) — a claim her lawyers are using to seek a chain reaction that leads to a class-action lawsuit. “We take the support of our content moderators incredibly seriously … ensuring that every person reviewing Facebook content is offered psychological support and wellness resources,” said Bertie Thomson, Facebook’s director of corporate communications, reported Reuters. Facebook uses more than 7,500 content reviewers worldwide to ensure its content is appropriate, but the company is pursuing artificial intelligence options that one day could replace human workers, reported Fox News.
