“Knowledge Sharing Network in a Community of Illicit Practice: A Cybermarket Subreddit Case”, K. Hazel Kwon, Weiwen Yu, Steve Kilar, Chun Shao, Kailey Broussard, Thomas Lutes2020-01-07 (; backlinks; similar)⁠:

Often neglected in the literature about communities of practice is the fact that online knowledge-sharing communities thrive among illicit collectives whose activities are stigmatized or outlawed.

This paper focuses on a knowledge-sharing community of users who engage in illegal practices by examining the ways in which the community’s network structure changes when a high-stakes, uncertain event—the July 2017 shutdown of the dark web market Alphabay—occurs. This study compares the discussion network structures in the subreddit /r/AlphaBay during pre-shutdown days (the “routine” period) and shutdown days (the “market defect” period) and offers a content analysis of the knowledge and resources shared by users during these periods.

Several differences were observed: (1) the network structure changed such that the network size grew while becoming more centralized; (2) new crisis-specific players emerged; (3) types of knowledge shared during the market defect period was qualitatively different from the routine period.
