Query: Studying Politically Vulnerable Communities Online: Ethical Dilemmas,
  Questions, and Solutions   This short article introduces the concept of political vulnerability for
social media researchers. How are traditional notions of harm challenged by
research subjects in politically vulnerable communities? Through a selection of
case studies, we explore some of the trade-offs, challenges, and questions
raised by research that seeks be robust and transparent while also preserving
anonymity and privacy, especially in high-stakes, politically fraught contexts.
