This book investigates social media regulation in Nigeria as an example for the Global South. It centres around political economy and theoretical insights drawn from studies into internet and social media regulation, the securitisation of online harms, and practical approaches to regulating social media content. Using a methodological approach that combines policy analysis, case studies, interviews, and social media analysis, the book contributes to and extends our knowledge of social media regulatory approaches in the Global South. It specifically introduces new concepts such as regulatory annexation to enable us to understand the regulatory environment in an African context and the several ways that social media users resist what is perceived as regulatory overreach in their struggle for digital freedom.
