Facebook requires people to send friend requests to each person you are requesting to be friends with. This setting helps keep peoples profile’s private. You can either “accept“ the friend request or “deny” the friend request, and if you want to find out more information about the person you can “ignore” the friend request. The only way you can view someone’s profile or personal information is if the person whose profile you are wishing to view accepts you. If someone adds you and you do not know him or her, or you have no mutual friends with, you can deny his or her friend request. If your best friend or family adds you, you can accept it and they can see all your personal information. For More Information Click Here!
