Why your friends are asked your email id if they want to send friend request to you in orkut?

In Orkut, users needed to provide an email address to send a friend request because it served as a unique identifier for each account. This system helped ensure that friend requests were sent to the correct person and facilitated communication between users. Additionally, using email addresses allowed for easier account management and verification. By requiring this information, Orkut aimed to enhance the user experience and maintain a secure social networking environment.
