The long read: As social media has become more inhospitable, the appeal of private online groups has grown. But they hold their own dangers – to those both inside and out.
WhatsApp, a messaging service, is cracking down further on fake news. Users will now only be allowed to forward a message to five groups (each group can be up to 256 people), down from 20. The limitation was first introduced in India last year after several mob lynchings there appeared to start after incendiary messages spread through the service.
In July, residents of a rural Indian town saw rumors of child kidnappers on WhatsApp. Then they beat five strangers to death.
