What does the fact that Tor users can’t edit wikipedia mean for the quality of the ``encyclopedia that anyone can edit?’’ How do captchas and blocking of anonymity services affect the experiences of Tor users when they are trying to contribute content? This talk will discuss the increasing limitations of active participation in the anonymous Internet and the findings of our interview study of Tor users and wikipedia editors concerning these issues. We believe that by understanding the contributions Tor users make—and that people denied access to anonymity tools don't make—we can help make the case for the value of anonymity online.
