Who should I send friend requests to on Facebook? – Friend Request lets you connect with people you may know which could be family, friends or colleagues. Facebook is made to connect people all around, but for certain reasons it is best of interest of the users to connect people they are familiar with. And not randomly, as this will help make you have common understanding and relate commonly.

Facebook recommend sending friend requests to people you know in real life, like your:

Friends.
Family.
Coworkers.
Classmates.

If you can’t send a friend request, you may have reached the 5,000 friend limit. To get updates in your News Feed from people you don’t know personally (ex: journalists, celebrities, political figures), try following them instead.

Note: We recommend only accepting friend requests from people you know. If you’re getting unwanted or inappropriate friend requests, you can report the account or block them. Learn about our policies by reading the Facebook Community Standards.
