Although many researchers, practitioners, and policymakers are concerned about identifying and characterizing online posting patterns of violent extremists prior to their engagement in violence offline, little is empirically known about their online patterns generally or differences in their patterns compared to their nonviolent counterpart particularly. In this study, we drew from a unique sample of violent and nonviolent right-wing extremists to develop and compare their online posting typologies (i.e. super-posters, committed, engaged, dabblers, and non-posters) in the largest white supremacy web-forum. We identified several noteworthy posting patterns that may assist law enforcement and intelligence agencies in identifying credible threats online.
