This document discusses ethics considerations for conducting social research in virtual worlds. It outlines some potential uses of virtual worlds for research, including as a tool for coordination, observing behavior, and studying community formation. However, it also notes challenges like participants not being accustomed to formal research and difficulties with identity verification and informed consent. The document presents a case study of a job interview study in Second Life and discusses ethics issues that could arise, like protecting social groups.
