Far-right and involuntary celibate extremists are said to populate an “online extremist ecosystem” of digital media environments. Online violent extremists are said to use this “ecosystem” to access outcomes that were previously unattainable. Yet there remained fundamental knowledge gaps in understanding the advantageous and limits of using ecosystems to understand and address far-right and involuntary celibate online violent extremism. This foundational theoretical and empirical study critically assessed whether ecosystems offered a greater or lesser understanding of these communities in the Australian and Canadian context and examined how individual involvement in these communities is shaped by digital media software and hardware.
