How to Limit FB Friend Requests
You can’t block friend requests completely, but you can tighten up your privacy settings to better define who is able to send you a request. To do this, change your privacy setting for friend requests to be Friends of friends. That way, the person must already be friends with one of your existing friends to request your friendship. This helps prevent strangers from seeing your Facebook profile.
How to Block a Friend Request
Stopping the request is another way to respond to unwanted friend requests. If you’d rather not follow the above steps, you can instead keep your profile open enough that strangers can still request your friendship, but you still have control over who you accept. You can block a friend request in two ways, depending on how persistent the user is at trying to be your friend:
Deny the Friend Request
The typical way to respond to a request to be friends on Facebook by someone you don’t want to associate with, is to simply deny the request. You have two options when someone sends you a request: choose Delete to block it, or Confirm to allow it. Select the notifications button at the top right of the website or app to view recent friend requests. To see all pending friend requests, visit the Friend Requests page on Facebook. If you’re using the app, tap Find Friends on your profile page, followed by Requests.
Block the User
Block the person on Facebook if you’ve denied their request, but they won’t stop sending other requests. This will stop them from messaging you, too, so if you really don’t want anything to do with the person, and denying their friend request won’t get them off your back, blocking is really your last option.
How to Stop a Friend Request
The above steps provide ways to stop a friend request coming to you from another person, but you can also do the opposite and stop your friend request you’ve sent to someone else. An easy way to do this is to view your sent friend requests on Facebook. From there you’ll be able to select Cancel request to stop it immediately.
