Friend requests that get denied

While I can understand why some would request to be added as a friend, I don't understand why the ones who have none of their own content and or none of my content is in their favorites and or they have an empty profile and or have everything in their profile set to private so I can't see a fucking thing and or they don't even send me a message on why they want to be my friend. These types of friend requests I will deny along with anyone who refuses to read my profile. Any homosexuals sending friend request will get denied and blocked! Why am I receiving friend requests from fat women or couples that the woman is fat when everyone can see in my favorites that I have no fat women? Can anyone explain these kinds of friend requests to me? What is your experiences with friend requests that are issues for you?
