Norm evolution and violation on Facebook

This study explores how norms on social network sites evolve over time and how violations of these norms impact individuals' self-presentational and relationship goals. Employing Expectancy Violations Theory (Burgoon, 1978) as a guiding framework, results from a series of focus groups suggest that both the content of the violation and the users' relationship to the violator impact how individuals react to negative violations. Specifically, acquaintances who engage in minor negative violations are ignored or hidden, while larger infractions (that could negatively impact the individual) result in deletion of the offending content and - in extreme cases - termination of the Facebook friendship. Negative violations from close friends (that did not impact participants' goals) resulted in confrontations, while similar violations from acquaintances were often ignored by participants in an effort to 'keep the peace.' Furthermore, positive violations were more likely to arise from acquaintances than close friends.
