Reddit communities increasingly adopt complex rule systems as they grow
The Bureaucratization of the Internet: Analyzing the Diffusion of Governance Regimes on Reddit (2011--2023)
Social and Information Networks
Summary
Online communities on Reddit create their own rules to keep things running smoothly. The authors analyzed Reddit’s rules from 2011 to 2023 and found that bigger communities tend to add more formal, detailed rules over time. New communities often start with standard rule templates, and rules spread mostly among communities sharing moderators or similar topics. However, communities competing for the same users often develop unique rules instead of copying each other. This shows how online governance becomes more bureaucratic as platforms expand.
What this means in practice
- •For online community managers: Design better moderation policies by understanding how community size influences rule complexity and adoption patterns.
- •For social media platform developers: Inform platform design to facilitate decentralized governance while managing rule spread and complexity among user groups.

Abstract
As online platforms scale, distributed communities must develop complex governance structures to maintain order. Reddit represents a unique experiment in this process: millions of subreddits manage their own digital commons, yet together they form an interconnected ecosystem of platform governance. Using a historical dataset of subreddit rules from 2011 to 2023, we apply computational methods to characterize that ecosystem and identify mechanisms driving change. We identify seven distinct governance regimes and document a platform-wide drift toward irreversible bureaucratization operating through two reinforcing dynamics: a ratchet effect among existing communities and a cohort shift in which new communities increasingly launch with pre-packaged regulatory frameworks. Using Dyadic Event History Analysis, we find that community scale is the dominant and universal predictor of rule adoption, independent of network exposure. Diffusion flows through two complementary channels: normative transmission via shared moderator networks and mimetic transmission among topically similar communities. However, mimetic copying is selective: it drives adoption of content rules addressing shared topical challenges while communities resist copying operational and behavioral rules. Additionally, communities with overlapping user bases differentiate rather than converge, consistent with ecological accounts of niche competition, and prestige-based contagion is firmly rejected. Together, these findings reveal decentralized platform governance as a stratified ecosystem in which lateral coordination, scale pressure, structural inertia, cohort effects, and episodic platform coercion jointly produce irreversible formalization with direct implications for platform management.
