WhatsApp on Wednesday rolled out a feature that will let users decide who can add them to WhatsApp groups
How to enable the feature
1. Go to settings in your app
2. Tap Account> Privacy > Groups
3. Select one of three options: 'Everyone,' 'My Contacts,' or 'My Contacts Except'
‘My Contacts’ means only users you have in your address book can add you to groups and ‘My Contacts Except’ provides additional control for who among your contacts can add you to a group
