WhatsApp has changed its group settings to include ‘everyone’ by default so people you don’t know can add you to a group without your knowing. These people may include scam messages, loan Sharks, etc. You can change its default settings as follows: 1. Go to WhatsApp: 2. Go into Settings 3. Go to Account 4. Go to Privacy 5. Go to Groups 6. Change from (Everyone) to (My Contacts) This is true. I have checked mine & all settings had been changed to everyone instead of my contacts.”
