Information Controls Fellow
Sam is an experienced researcher focusing on the interplay between digital politics of the Chinese Communist Party and its effects on society and global power dynamics. Sam’s work spans a broad array of topics including human rights, internet governance, and cyber security within China’s digital landscape.
The project: The Great Firewall of China has adopted new features. Chinese social media platforms increasingly deploy new access barriers that can exclude entire countries. These barriers are built by first linking all social media accounts to mobile phone numbers and then only allowing selected prefixes (e.g. +86 for China) to register.
Phone number-based registration systems allow platforms to limit access to users of certain regions or only to users from China. If access is limited to holders of only certain prefixes (such as +86), new users and users who have lost access to their accounts cannot (re-)join those online communities.
In his report Blocked By Numbers: The Impact of Real-Name registration Policies on Transnational Access Barriers to Chinese Social Media Apps (in EN and CH), Sam provided a comprehensive understanding of the magnitude of these restrictive practices, their global patterns, and the motives behind these phone number-based discrimination systems. Throughout the project, Sam was hosted by GreatFire, and investigated the extent to which platforms remain accessible globally, the patterns of regional exclusion, and the policy background driving these limitations. As these restrictions are particularly impactful in regions with significant Chinese diaspora communities, research or business networks, and political ties, the project also identified the most affected groups.
