摘要：In its ethics guidelines, the Association of Internet Researchers advocates a bottom-up, case-based approach to research ethics, one that emphasizes that ethical judgement must be based on a sensible examination of the unique object and circumstances of a study, its research questions, the data involved, and the expected analysis and reporting of results, along with the possible ethical dilemmas arising from the case. This article clarifies and illustrates the mind-set and process of such a bottom-up approach to internet research ethics. Two ethics concepts to think with, namely ‘the distance principle’, and the notion of ‘perceived privacy’, are introduced and applied in a concrete empirical internet study, in which web archives based on personal communications on social media formed the main body of data. The empirical case example serves to highlight the unique challenges of internet research ethics, in light of the blurring boundaries between text and person, and between private and public on the internet, with profound implications and challenges for the definition of human subjects, privacy, and so on.
