“A group of Facebook engineers identified a ‘massive ranking failure’ that exposed as much as half of all News Feed views to ‘integrity risks’ over the past six months,” The Verge reports.
“The engineers first noticed the issue last October, when a sudden surge of misinformation began flowing through the News Feed… Instead of suppressing dubious posts reviewed by the company’s network of outside fact-checkers, the News Feed was instead giving the posts distribution, spiking views by as much as 30 percent globally.”
