Social networking sites make it easy for users to connect with, follow, or "like" each other. Such a mechanism promotes positive connections and helps a social networking site to grow without direct belligerent or negative encounters. This type of one-way connections makes no distinction between indifference and dislike; in other words, two users have only, by default, positive connections. However, it is apparent that as one's network grows, some users might not be benevolent toward each other, or negative links could form, though not explicitly stated. In this talk, I assess the need for discovering such hidden negative links, explore ways of finding negative links, and show the significance of negative links in social media applications.
