Social network users sometimes experience bullying (i.e., insults, sarcasm, intense language) through postings on their profile pages. Bullying has become a distinct characteristic of CMC and has been interpreted by many providers to be unsuitably hostile. These behaviors range from personal attacks to a mild form of teasing, and a number of researchers have found that they can serve an unintended purpose online. In his examination of Internet mailing lists, Hongiie Wang found that bullying was one of the only tools users had to enforce the informal rules they believed to exist. It was used as a form of policing or a method to “educate the ignorant” about the rules and norms of the online community. Despite the unintended consequences that bullying has to facilitate the norms and rules for Internet groups, most social networks attempt to hinder this practice by establishing their own explicit norms for the behavior of members.
