Security Behavior of Pro-ISIS Groups on Social Media
Since the team had tracked these groups daily, researchers could observe the tactics that pro-ISIS groups use to evade authorities. They found that 15 percent of groups changed their names during the study period, and 7 percent flipped their visibility from public to members only. Another 4 percent underwent what the researchers called reincarnation. That means the group disappeared completely but popped up later under a new name and earned more than 60 percent of its original followers back.
The researchers compared these behaviors in the pro-ISIS groups to the behaviors of other social groups made up of protestors or social activists (the entire project began in 2013 with a focus on predicting periods of social unrest). The pro-ISIS groups employed more of these strategies, presumably because the groups were under more pressure to evolve as authorities sought to shut them down.
