1. Set yourself a rule to add friends only, don’t add strangers.
  2. Look at the name and picture carefully. Also click on the “Name” to see the complete profile. If the profile has little details, then chances are it could be a made-up account.
  3. Look for the “You have no friends in common” line. If this person is a friend of yours, there should be some connections.
  4. If this person who’s inviting you is a brand new Facebook user with no friends, then pick up a phone. If he/she is a real friend, you’d probably have something in common to chat about. Call him/her up and find out if there’s a genuine request from them. Always be careful rather than be sorry.
