Reddit Rules and Rulers: Quantifying the Link Between Rules and Perceptions of Governance across Thousands of Communities
Leon Leibmann, Galen Weld, Amy X. Zhang, Tim Althoff

TL;DR
This study analyzes over 67,000 Reddit community rules over five years, classifies them, and links specific rule types to positive perceptions of governance, revealing immediate but transient effects of rule changes.
Contribution
It provides the largest dataset of community rules, a taxonomy for classifying rules, and insights into how different rules impact community perceptions over time.
Findings
Rules about participation, content formatting, and commercial activities are linked to positive perceptions.
Adding new rules improves perceptions immediately, but the effect diminishes after six months.
The study offers a public classification model and dataset for future research.
Abstract
Rules are a critical component of the functioning of nearly every online community, yet it is challenging for community moderators to make data-driven decisions about what rules to set for their communities. The connection between a community's rules and how its membership feels about its governance is not well understood. In this work, we conduct the largest-to-date analysis of rules on Reddit, collecting a set of 67,545 unique rules across 5,225 communities which collectively account for more than 67% of all content on Reddit. More than just a point-in-time study, our work measures how communities change their rules over a 5+ year period. We develop a method to classify these rules using a taxonomy of 17 key attributes extended from previous work. We assess what types of rules are most prevalent, how rules are phrased, and how they vary across communities of different types. Using a…
