There is an emerging consensus that ideologically-based narratives play a central role in encouraging and sustaining radicalization to violence, and that preventing, arresting, or reversing radicalization requires some means by which to address the effects of these narratives. Countering violent extremism (CVE) is a broad umbrella phrase that covers a wide array of approaches that have been advanced to reduce the radicalizing effects of extremist narratives. There is considerably less agreement, however, regarding the most appropriate means by which the mitigation of extremist narratives might best be accomplished. An important emerging area of interest is the role of the Internet, both as a forum through which narratives are transmitted and as an avenue for delivering CVE programs. At present, very little is known about which principles and practices should inform online CVE initiatives. This study attempts to establish a foundation and framework for these programs: first, by identifying the concepts and constructs which may be most relevant to countering violent extremism online, and second, by examining the available material from six online CVE programs in relation to these concepts. This examination suggests that these programs are lacking strong theoretical foundations and do not address important elements of radicalization, such as contextual factors or identity issues. It is important that future iterations of CVE programs consider not just the specific content of the narratives, but also take into account why these narratives have resonance for particular individuals.

In recent years, extremists have increasingly turned to online spaces to distribute propaganda and as a recruitment tool. While there is a clear need for governments and social media companies to respond to these efforts, such responses also bring with them a set of ethical challenges. This paper provides an ethical analysis of key policy responses to online extremist propaganda. It identifies the ethical challenges faced by policy responses and details the ethical foundations on which such policies can potentially be justified in a modern liberal democracy. We also offer an ethical framework in which policy responses to online extremism in liberal democracies can be grounded, setting clear parameters upon which future policies can be built in a fast-changing online environment.

On July 1, 2021, a new social network modeled after Twitter was launched by former Trump spokesman Jason Miller, with assistance and promotion by exiled Chinese businessman Miles Guo, form Trump strategist Steve Bannon, and others. Today, the Stanford Internet Observatory is releasing the first comprehensive analysis of the new platform. We chart the growth of Gettr over its first month, examining the user community, content, structure and dynamics. We also highlight some of the perils of launching such a network without trust and safety measures in place: the proliferation of gratuitous adult content, spam and, unfortunately, child exploitation imagery, all of which could be caught by cursory automated scanning systems.

The advent of social media has led to an increased concern over its potential to propagate hate speech and misinformation, which, in addition to contributing to prejudice and discrimination, has been suspected of playing a role in increasing social violence and crimes in the United States. While literature has shown the existence of an association between posting hate speech and misinformation online and certain personality traits of posters, the general relationship and relevance of online hate speech/misinformation in the context of overall psychological wellbeing of posters remain elusive. One difficulty lies in the lack of adequate data analytics tools capable of adequately analyzing the massive amount of social media posts to uncover the underlying hidden links. Recent progresses in machine learning and large language models such as ChatGPT have made such an analysis possible. In this study, we collected thousands of posts from carefully selected communities on the social media site Reddit. We then utilized OpenAI’s GPT3 to derive embeddings of these posts, which are high-dimensional real-numbered vectors that presumably represent the hidden semantics of posts. We then performed various machine-learning classifications based on these embeddings in order to understand the role of hate speech/misinformation in various communities. Finally, a topological data analysis (TDA) was applied to the embeddings to obtain a visual map connecting online hate speech, misinformation, various psychiatric disorders, and general mental health.

Online video sharing platforms such as YouTube contains several videos and users promoting hate and extremism. Due to low barrier to publication and anonymity, YouTube is misused as a platform by some users and communities to post negative videos disseminating hatred against a particular religion, country or person. We formulate the problem of identification of such malicious videos as a search problem and present a focused-crawler based approach consisting of various components performing several tasks: search strategy or algorithm, node similarity computation metric, learning from exemplary profiles serving as training data, stopping criterion, node classifier and queue manager. We implement two versions of the focused crawler: best-first search and shark search. We conduct a series of experiments by varying the seed, number of n-grams in the language model based comparer, similarity threshold for the classifier and present the results of the experiments using standard Information Retrieval metrics such as precision, recall and F-measure. The accuracy of the proposed solution on the sample dataset is 69% and 74% for the best-first and shark search respectively. We perform characterization study (by manual and visual inspection) of the anti-India hate and extremism promoting videos retrieved by the focused crawler based on terms present in the title of the videos, YouTube category, average length of videos, content focus and target audience. We present the result of applying Social Network Analysis based measures to extract communities and identify core and influential users.
