Looking forward to AoIR2017 in Tartu! I will present a part of my research on hacker cultures which is particularly important to me – and is likewise giving me a headache sometimes: ethical decisions and moral issues concerning participants’ interests and privacy. The hackers and makers I met so far were often very generous with the information they share – online as well as in interviews. But when sharing online, how aware are they of the contexts in which their statements can be published? And how do you deal with statements that address third persons? In my talk “Tracing Controversies in Hacker Networks”, I will therefore address the ethics of research on hacker communities. Here’s a preview of some of the issues that I will touch upon in my presentation.
