Devin Coldewey. Study finds Reddit's controversial ban of its most toxic subreddits actually worked. TechCrunch, September 2017. URL: https://techcrunch.com/2017/09/11/study-finds-reddits-controversial-ban-of-its-most-toxic-subreddits-actually-worked/ (visited on 2023-12-08).
In a field dominated by philosophy, the Coldewey article about the 2017 Reddit subreddit bans are a relatively few pieces of empirical evidence. While banning toxic communities may have decreased overall hate speech across platforms (i.e., users did not simply migrate and reestablish at the same levels) this was empirically measured; therefore, this will provide an objective measure that does mitigate the motivated reasoner problem when evaluating moderation actions from a Rawlsian perspective. However, there are limitations to the consequences-based "escape" mechanism - while the Coldewey article quantifies the reduction in hate speech as a result of the ban, it does not determine whether or not those who were banned had their attitudes toward hate speech changed as a result of being banned. That is a far more difficult measurement to make.
