Meta terminology
CEI
Child Exploitative Imagery
Meta's policy and enforcement category for imagery that sexually exploits children, tracked separately from Minor Sexualization and from Inappropriate Interactions with Children. The source document has executives weighing whether to limit the CEI figure published in the Community Standards Enforcement Report to Facebook only, "to avoid a step-change some time in the future when we lose access to private messaging", at a point when by their own estimate "almost 90%" of egregious CEI content was on Messenger.
