Researchers have previously explored how right-wing extremists build a collective identity online by targeting their perceived “threat,” but little is known about how this “us” versus “them” dynamic evolves over time. This study uses a sentiment analysis-based algorithm that adapts criminal career measures, as well as semi-parametric group-based modeling, to evaluate how users’ anti-Semitic, anti-Black, and anti-LGBTQ posting behaviors develop on a sub-forum of the most conspicuous white supremacy forum. The results highlight the extent to which authors target their key adversaries over time, as well as the applicability of a criminal career approach in measuring radical posting trajectories online.

Terrorist groups like the Islamic State of Iraq and Syria (ISIS) have exploited social media such as Twitter to spread their propaganda and to recruit new members. In this work we study the extent to which ISIS is able to spread their message beyond their immediate supporters. Are they operating in their own sphere with limited interaction with the overall community? Or are they well rooted among normal users? We find that three-quarters of the interactions ISIS received on Twitter in 2015 actually came from eventually suspended accounts raising questions about the potential number of ISIS-related accounts and how organic ISIS audience is. Towards tackling these questions, we have created a unique dataset of 17 million ISIS-related tweets posted in 2015. This dataset is available for research purposes upon request.

We are delighted to announce the launch of the final report of the Mechachal project, one of first academic studies to contextually examine how hate speech emerges and disseminates in social media.

Focusing on Ethiopia, and in collaboration with Addis Ababa University, the research team examined thousands of comments made by Ethiopians on Facebook during four months around the time of the country’s general election. Hate speech’ –defined as statements to incite others to discriminate or act against individuals or groups on grounds of their ethnicity, nationality, religion or gender – was found in just 0.7% of overall statements in the representative sample. The paper says the findings may have wide implications for the many countries trying to address growing concerns about the role played by social media in promoting radicalisation or violence.

Ethiopia represented an exceptional case study because of its distinct languages, which allowed the research team to gain a realistic sample of the overall online debates focused on one country. The research team analysed Facebook statements made by Ethiopians, both in their homeland and abroad, in the run-up to and just after the general election on 24 May 2015. Fans or followers, rather than people with any real influence online, were found to be mainly responsible for the violent or aggressive speech that appeared on Facebook pages in the sample.

It appears these individuals use Facebook to vent their anger against more powerful sections of society. Around 18% of total comments in the sample were written by fans or followers compared with 11% of comments made by highly influential speakers (the owners of web pages). One fifth (21.8%) of hostile comments were grounded in political differences, only slightly higher than the overall average of 21.4% of all conversations containing hostile comments. Religion and ethnicity provoked fewer hostile comments (10% and 14% of overall comments in sample respectively).

How does the internet affect the radicalisation of extreme-right lone actor terrorists? In the absence of an established theoretical model, this article identifies six mechanisms seen as particularly relevant for explaining online radicalisation. Having first reviewed a larger set of relevant lone actor terrorists, the study traces these mechanisms in three selected cases where the internet was reportedly used extensively during radicalisation. The findings show that the internet primarily facilitated radicalisation through information provision, as well as amplifying group polarisation and legitimising extreme ideology and violence through echoing. In all three cases, radicalisation was also affected considerably by offline push-factors that through their presence made extreme online messages more impactful. The results challenge the view that offline interaction is necessary for radicalisation to occur but also the view that online influence itself is sufficient.
