Facebook temporarily suspends Bernie Sanders groups owing to 'glitch'

Filipino presidential supporters also affected by bug, sparking anger at opponents

A bug in Facebook's anti-spam algorithm has been accidentally suspending groups on the social network, sparking anger from the groups' founders and conspiracy theories from some of their followers.

On Monday night, six pro-Bernie Sanders groups were temporarily suspended by Facebook. A day later, five Facebook groups supporting Filipino presidential candidate Rodrigo Duterte, with a total membership of more than 3 million people, were also taken down for a short period.
