Extra "Not Now" Option to block a Facebooker for Future Friend Request

An Extra Option added to Facebook "Not Now" button which may resist future friend requests from an unknown facebook user.

As you know, facebook makes your friend request hidden when you mark a friend request as "not now" but there's also an extra option added to "not now". That is, it displays a question, asking you "Do you know (Name) outside of Facebook?" and gives you two option "Yes" or "No". If you confirm "yes", then it'll keep the request hidden and later you can accept the request. But if you confirm "no", then it may resist that user for future friend request.
