Social media platforms are increasingly recognised as both arenas and accelerators of radicalisation, misinformation, and extremist mobilisation. But how has the evidence evolved? What role does disinformation play in amplifying extremist narratives, and how do online spaces, from mainstream platforms to niche forums, contribute to the radicalisation process?

It explores emerging trends, such as far-right online violence, the dynamics of ‘chan’ cultures, hybrid identities, and the spread of disinformation, offering valuable evidence to support policy and intervention strategies.
