论文摘要
Subreddit R/The_donald反复谴责为一个有毒和行为不端的在线社区，其原因是Reddit管理员面临的一系列日益限制的节制干预措施。它于2019年6月被隔离，于2020年2月受到限制，最终于2020年6月被禁止，但是尽管对此事进行了预先努力，但这种干预序列的影响仍不清楚。在这项工作中，我们遵循一种多维因果推理方法来研究数据，其中包含2年时间范围内的1500万个帖子，以检查Subreddit内部和外部此类干预措施的影响。我们发现干预措施大大减少了有问题的用户的活动。但是，干预措施也导致毒性增加，并导致用户分享更加两极化和更少的事实新闻。此外，限制的效果比隔离区更强，R/The_donald的核心用户效果比其他用户更强。总体而言，我们的结果提供了证据，表明干预措施具有不同的作用，并描绘了社区级节制策略的后果的细微效果。最后，我们通过思考维持在线平台的挑战以及对适度干预措施的设计和部署的影响。
The subreddit r/The_Donald was repeatedly denounced as a toxic and misbehaving online community, reasons for which it faced a sequence of increasingly constraining moderation interventions by Reddit administrators. It was quarantined in June 2019, restricted in February 2020, and finally banned in June 2020, but despite precursory work on the matter, the effects of this sequence of interventions are still unclear. In this work, we follow a multidimensional causal inference approach to study data containing more than 15M posts made in a time frame of 2 years, to examine the effects of such interventions inside and outside of the subreddit. We find that the interventions greatly reduced the activity of problematic users. However, the interventions also caused an increase in toxicity and led users to share more polarized and less factual news. In addition, the restriction had stronger effects than the quarantine, and core users of r/The_Donald suffered stronger effects than the rest of users. Overall, our results provide evidence that the interventions had mixed effects and paint a nuanced picture of the consequences of community-level moderation strategies. We conclude by reflecting on the challenges of policing online platforms and on the implications for the design and deployment of moderation interventions.
