This is one of two panels organized by the AoIR Ethics Working Committee. This panel on “Platform & Pragmatic Challenges” collects four papers exploring a set of unique research contexts and pragmatic challenges that confront the internet research community. These contributions provide systematic analyses of these growing research contexts and a review of the pragmatic challenges faced by internet researchers attempting to ensure compliance with ethical best practices. The platform and pragmatic challenges addressed by this collection of papers include: how the (mis)appropriation of social media ads in academia raises ethical concerns for participants and researchers in terms of safety, privacy, and right to self-determination; understanding the intrinsic relationship that exists between ethical “hurdles” and platform affordances when conducting research on Instagram; investigating how ethics has been addressed in the explosion of twitter-based research and the challenges around the use of public social media data for research; and an analysis of so-called research “safe spaces” where authorized researchers are able to directly access and analyse potentially sensitive and identifiable data. These papers are among those under consideration for publication in a special issue of the Journal of Information, Communication and Ethics in Society associated with the AoIR Ethics Working Committee and AoIR2023.
