Friending on Facebook helps you stay connected with people you care about. Adding a friend means you may see each other’s activity in News Feed, Stories and Photos.
When you want to add a friend on Facebook, keep in mind:
You can control who can friend and follow you by editing your privacy settings.
If you don’t want someone to see you on Facebook, learn how to unfriend or block them.
You can have up to 5,000 friends at a time.
If you’d like to see updates from people you find interesting but don’t know personally, like a journalist or celebrity, try following them instead. If you’re getting unwanted or inappropriate friend requests, you can report the account.
