An alleged bug (intentional or mistake?) in Facebook’s program exposed the identities of its moderators who were overseeing the group pages containing terrorist propaganda, sexual content, and “hate speech.” The bug placed the identities of the moderators as notifications on those pages, allowing anyone with admin privileges for the pages to see who at Facebook was watching their posts.
According to the Guardian, “Of the 1,000 affected workers, around 40 worked in a counter-terrorism unit based at Facebook’s European headquarters in Dublin, Ireland. Six of those were assessed to be “high priority” victims of the mistake after Facebook concluded their personal profiles were likely viewed by potential terrorists.” Their identities were seen by terrorists with ties to “ISIS, Hezbollah and the Kurdistan Workers Party.”
Facebook has now fixed the problem, but the six moderators whose profiles were definitely seen by terrorists are in hiding for fear of their lives.
