Every user and page on the network has a Global Reputation Score (GRS) calculated by adding or subtracting earned or lost points in real-time and represents the user or page lifetime Reputation Score. The GRS is translated into a rank that is displayed next to the user or page name. In the future, it will also be displayed transparently to the network users.
