If you friend request someone on facebook,will it tell you if they say no
If you send friend request to someone in facebook you will not know if they accepted your friend request or not. Only results on accepted friend request are appearing on the recent news tab.
No. If they don't accept your friend request, you just won't be able to access their profile.
Joe says no
You will not be able to know if they deny it other than you won't be able to look / comment on their profile & it will give you the ability to send them a request.
