Recent acts of terrorism and hate crimes have prompted a renewed focus on the possible links between internet content and offline violence. While some have focused on the role that social media companies play in moderating user-generated content, others have called for Congress to pass laws regulating online content promoting terrorism or violence. Proposals related to government action of this nature raise significant free speech questions, including (1) the reach of the First Amendment’s protections when it comes to foreign nationals posting online content from abroad; (2) the scope of so-called “unprotected” categories of speech developed long before the advent of the internet; and (3) the judicial standards that limit how the government can craft or enforce laws to preserve national security and prevent violence.

There has been an increased focus on reducing hate, harassment, and extremist exploitation in digital games through solutions from community management, trust and safety, and design perspectives. Despite this attention, the industry lacks basic standards around these issues and efforts in this area are stymied by the ubiquity of “toxic gamer culture” and fears in the industry about discussing extremism and hate within games. Today, a patchwork of strategies and tools exist. In this study, focus groups with industry professionals were conducted to increase understanding of industry professional’s perceptions of these problems and solutions. Several primary themes regarding solutions emerged: game and social system design strategies, moderation and player report strategies, and wish list solutions.

In an era of social media, the lines between physical and virtual realities have become blurred. This is especially evident in recruitment activities by violent extremists. This article compares five case studies from the white power and militia movements to learn how extremists attract new members. The findings suggest that recruitment occurs through iterative interactions in virtual and physical spaces. These spaces are not isolated to a single movement; individuals instead move between them. The findings did not reveal a divergence between civilian vs military recruits. Nevertheless, more research is needed on the extent to which veterans recruit their peers.

Online social media platforms such as Twitter have been found to be misused by extremist groups, including Islamic State of Iraq and Syria (ISIS), who attract and recruit social media users. To prevent their influence from expanding in the online social media platforms, it is required to understand the online behaviors of these extremist group users and their followers, for predicting and identifying potential security threats. We present an empirical study about ISIS followers’ online behaviors on Twitter, proposing to classify their tweets in terms of political and subjectivity polarities. We first develop a supervised classification model for the polarity classification, based on natural language processing and clustering methods. We then develop a statistical analysis of term-polarity correlations, which leads us to successfully observe ISIS followers’ online behaviors, which are in line with the reports of experts.
