My social media engagement with research interlocutors is shaped by my positionality as a ‘halfie’ anthropologist based abroad who conducts ethnographic research on violence and peacemaking in the Philippines and the diaspora. On the one hand, social media connectivity facilitates certain research processes, networking, activism, and solidarity building. Yet with social media's security issues and amid shifting political tides, such connectivity poses ethical and security risks, resulting in social media-specific ethical concerns. I demonstrate these points through an account of my engagement with Facebook, a ubiquitous platform for communicating among Filipinos. In the process, I reflect on some of the ways in which social media connectivity between researcher and interlocutors reconfigures the relationality, temporality, hierarchies, and affect of the ethnographic ‘field’.
