Online Social Media (OSM) websites have attracted millions of users by enabling them to socially interact in ways that were not possible before. While the explosion of OSM use has had many benefits, it also has a darker side where an individual's personal information can potentially be misused. This study develops and tests an empirical model based on a theoretical lens provided by Protection M...

Few but mentionable studies have been conducted in typifying the Online Social Media (OSM) users. Studies on innovations taking place within the OSM environment are also very much found.
