WhatsApp has added a new feature that stops people from automatically adding you to groups, letting you decide which ones you want to join. Until now, once someone has your contact details they can add you to a group chat without your permission. Being added to a group chat could potentially expose your phone number to hundreds of people – a cause for privacy concerns. Choosing 'My Contacts' will limit group-adding to people in your phone contacts – forcing everyone else to invite you first. 'WhatsApp groups continue to connect family, friends, coworkers, classmates and more,' a spokesman for WhatsApp said in a statement.
