A virtual contact, friend, colleague or passive connection that join all your social networks (Facebook, Myspace, Pinterest, LinkedIn, Digg, Stumbleupon and Google+) and comments, likes, plus one or shares all your posts regardless of rhyme or reason.
These individuals are every where you turn and tend to be individuals you have never met before. They formulate opinions based on everything in your life. They begin to live vicariously through you.
My social media stalker has commented on my last ten Google + posts and the last 15 posts on Facebook.
