Benjamin Mako Hill: What makes online groups vulnerable to governance capture?

Note: I have not published blog posts about my academic papers over the past few years. To ensure that my blog contains a more comprehensive record of my published papers and to surface these for folks who missed them, I will be periodically (re)publishing blog posts about some “older” published projects. This post is closely based on a previously published post by Zarine Kharazian on the Community Data Science Blog.

For nearly a decade, the Croatian language version of Wikipedia was run by a cabal of far-right nationalists who edited articles in ways that promoted fringe political ideas and involved cases of historical revisionism related to the Ustaše regime, a fascist movement that ruled the Nazi puppet state called the Independent State of Croatia during World War II. This cabal seized complete control of the encyclopedia’s governance, banned and blocked those who disagreed with them, and operated a network of fake accounts to create the appearance of grassroots support for their policies.

Thankfully, Croatian Wikipedia appears to be an outlier. Though both the Croatian and Serbian language editions have been documented to contain nationalist bias and historical revisionism, Croatian Wikipedia seems unique among Wikipedia editions in the extent to which its governance institutions were captured by a small group of users.

The situation in Croatian Wikipedia was well documented and is now largely fixed, but we still know very little about why it was taken over, while other language editions seem to have rebuffed similar capture attempts. In a paper published in the Proceedings of the ACM: Human-Computer Interaction (CSCW), Zarine Kharazian, Kate Starbird, and I present an interview-based study that provides an explanation for why Croatian was captured while several other editions facing similar contexts and threats fared better.

Based on insights from interviews with 15 participants from both the Croatian and Serbian Wikipedia projects and from the broader Wikimedia movement, we arrived at three propositions that, together, help explain why Croatian Wikipedia succumbed to capture while Serbian Wikipedia did not: 

1. Perceived Value as a Target. Is the project worth expending the effort to capture?
2. Bureaucratic Openness. How easy is it for contributors outside the core founding team to ascend to local governance positions?
3. Institutional Formalization. To what degree does the project prefer personalistic, informal forms of organization over formal ones?

The conceptual model from our paper, visualizing possible institutional configurations among Wikipedia projects that affect the risk of governance capture. 

We found that both Croatian and Serbian Wikipedias were attractive targets for far-right nationalist capture due to their sizable readership and resonance with national identity. However, we also found that the two projects diverged early in their trajectories in how open they remained to new contributors ascending to local governance positions and in the degree to which they privileged informal relationships over formal rules and processes as the project’s organizing principles. Ultimately, Croatian’s relative lack of bureaucratic openness and rules constraining administrator behavior created a window of opportunity for a motivated contingent of editors to seize control of the governance mechanisms of the project. 

Though our empirical setting was Wikipedia, our theoretical model may offer insight into the challenges faced by self-governed online communities more broadly. As interest in decentralized alternatives to Facebook and X (formerly Twitter) grows, communities on these sites will likely face similar threats from motivated actors. Understanding the vulnerabilities inherent in these self-governing systems is crucial to building resilient defenses against threats like disinformation. 

For more details on our findings, take a look at the published version of our paper.
