This study examines the prevalence, intensity, and diffusion of toxic messages across four social media platforms (X, Facebook, Instagram, and TikTok), focusing on five discursively stigmatised target groups: migrants, Muslims, Roma people, Jews, and LGBTI people. Attention is given to posts that co-mention two or more of these groups within the same message. Throughout the manuscript, we refer to these cases as “intersectional patterns” in the s…
Migrant by Proxy: How Big Data Defines and Redefines Human Mobility
In big data systems, migrants rarely appear as self-identified social actors. Instead, they are rendered through proxies such as social media traces, mobile phone records, or online behavioural signals. We introduce the concept of the migrant by proxy to examine how such indicators do more than approximate migration: they shape what migration becomes measurable, visible, and governable. Across discursive, behavioural, infrastructural, and demogra…

This paper aims to anticipate violent acts by analyzing online hate speech (hatred, toxicity, and sentiment) and comparing it to offline hate crime. The dataset for this prere…
