Creeper 

a person fully devoid of any social skills or grace, who social network stalks people, or makes observations due to a thorough lack of any life of their own; this person frequently "befriends" people who they are only tangentially connected in order to sadly try to prove that they are relevant.

My pseudo friend Herbert is such a creeper, he friends my friends and actually thinks he's relevant. He needs to join a Community Band, that seems to be more his speed.
