If you use your Public Profile, Snapchatters are still able to add you as a friend by adding you from your Public Profile, searching for you, etc. These friend request will typically appear in the 'Added Me' section.
Snapchatters can follow to you from Spotlight, Snap Map, Discover or by tapping the 'Add' button on your Public Profile. Unlike friend requests sent from Search and Quick Add, you will not receive a notification for new followers from Spotlight, Snap Map or Discover.
Pro Tip 💡 If you add a Public Profile, you'll be adding that Public Profile owner as a friend, and you'll become friends with them if they add you back.
Please Note: Your Public Profile does not change any existing contact settings or 'My Friends' or 'Custom' My story privacy settings.
