Abstract
The problem of online antisocial behavior is increasingly attracting public attention and is compromising the quality of online communities. Previous research on online hostility looked at different aspects of the problem such as its definition, classification, or studying specific case studies, however, the impact is still not clear. In this paper, we propose a new model to investigate the impact of antisocial behavior online, the model is based on the Unified Theory of Acceptance and Use of Technology (UTAUT), our model integrates the perception of antisocial behavior as a risk factor along with other factors drawn from sociology. Initial validation of our model was conducted through expert reviews, the reviews include interviews with experts from computer science, sociology, and psychology, who were asked to consider its application to Twitter (as one of the controversial cyberspaces when it comes to antisocial behavior). The results of both quantitative and qualitative analysis of the expert reviews show strong support to the proposed model.
