” We already knew that Facebook moved quickly on Thursday to stop videos of the New Zealand mass shooting from spreading, but now we have some actual numbers.
In a public statement and identical series of tweets dispensed by Facebook Newsroom, the company confirms that 1.5 million videos were removed in the first 24 hours following the terror attack on two New Zealand mosques that left 50 dead and 50 injured as of Sunday. Of those, 1.2 million were stopped before they were even uploaded.”
