There are several reasons why someone might not be able to friend another person on Facebook:
- The person may have blocked you, which prevents you from sending a friend request or seeing their profile fully.
- The person has set their privacy settings to restrict who can send friend requests, such as allowing only friends of friends or disabling friend requests altogether.
- The person has reached the maximum friend limit on Facebook (5,000 friends), so you can only follow them rather than friend them.
- You may have been temporarily restricted by Facebook from sending friend requests due to repeated violations of guidelines.
- The friend request could be pending, denied, or deleted by the recipient, sometimes with a delay or glitch in the display of request status.
- Either party might be taking a break from Facebook or not actively checking friend requests.
- You or the other person might have accidentally blocked each other or changed relevant account settings affecting the ability to send or receive friend requests.
To troubleshoot, check if the "Add Friend" button is visible on the person's profile, review your block list, and ensure your own friend request settings allow sending requests to everyone. Also, consider that friend requests may be intentionally ignored or restricted by the recipient.
