Natural disasters, elections, climate changes, insurrections, pandemics, and new technologies are rocking the world. People talk about events, both these massive ones and much smaller ones, online. Social media platforms, search engines and websites have become the window through which these events are viewed and interpreted. Those on social media seek and shape information, build and join communities, often with impacts in the physical world. One consequence is an online breeding ground for growing and disseminating disinformation, hate speech and extremism. In this conference we ask: How is this done? Who is doing it? Why is it being done? What are the social consequences? How can it be countered? IDeaS will host it's second hybrid conference on disinformation, hate speech, and extremism online in September 2024. This conference aims to advance the science of social-cybersecurity through research and applications in this area. We invite papers that address questions related to disinformation, hate speech and extremism on line. We are particularly interested in papers that touch on the role that disinformation, hate speech and extremism are playing in events such as the vaccine roll out, presidential elections around the world, civil conflict, and community resilience. Policy, empirical, qualitative, data science and simulation papers are of equal interest. The conference will include: invited panels, posters, and regular talks. There will also be the opportunity for those interested to demo their technologies.
