这篇论文研究 Reddit 内容删除后的解释是否影响用户后续行为。基于 3200 万条帖子的分析显示，向用户提供删除解释能显著降低其帖子再次被删除的概率，且人工版主的解释并不比机器人自动解释更有效。作者认为解释机制在社区管理中被低估，值得投入资源。
HN 关注点：内容审核与平台治理，论文用大规模数据验证了'给用户解释'这一看似常识的做法确实有效，引发对审核透明度和自动化工具的讨论。

补充贴出论文摘要：大规模数据显示删除解释能降低未来删帖率，人工解释不比机器人解释更有效
论文标题为《审核透明度真的重要吗？Reddit 内容删除解释对用户行为的影响》。基于 3200 万条 Reddit 帖子，作者刻画了删除解释的类型，并将其与用户后续行为（未来发帖和未来被删帖）关联。主题建模显示解释往往起到教育用户了解社区规范的作用；回归模型表明提供删除解释能降低未来帖子被删的几率。人工版主的解释在降低未来删帖方面并不比机器人解释有显著优势。结论：删除解释在审核实践中可能被低估，社区管理者值得投入时间资源。

Study title: "Does Transparency in Moderation Really Matter?: User Behavior After Content Removal Explanations on Reddit". Abstract: > When posts are removed on a social media platform, users may or may not receive an explanation. What kinds of explanations are provided? Do those explanations matter? Using a sample of 32 million Reddit posts, we characterize the removal explanations that are provided to Redditors, and link them to measures of subsequent user behaviors—including future post submissions and future post removals. Adopting a topic modeling approach, we show that removal explanations often provide information that educate users about the social norms of the community, thereby (theoretically) preparing them to become a productive member. We build regression models that show evidence of removal explanations playing a role in future user activity. Most importantly, we show that offering explanations for content moderation reduces the odds of future post removals. Additionally, explanations provided by human moderators did not have a significant advantage over explanations provided by bots for reducing future post removals. We propose design solutions that can promote the efficient use of explanation mechanisms, reflecting on how automated moderation tools can contribute to this space. Overall, our findings suggest that removal explanations may be under-utilized in moderation practices, and it is potentially worthwhile for community managers to invest time and resources into providing them.
补充亲历经验：让被封用户自己指出违反的规则，比平台单方面解释更有效
论文有趣但结论 fairly obvious。一个假设是解释必须由'公司'提供，其实让用户自己解释可能更好。我以前做管理时简化了服务条款，封禁时把球踢回给用户：'想恢复账号，请指出你违反了 TOS 的哪条规则。'效果出乎意料地好——在乎账号的人很快自己找到问题，也证明他们读过 TOS；屡犯者则是故意捣乱，直接保持封禁。前提是 TOS 得让人看得懂。另一个值得研究的问题是：TOS 复杂到什么程度就只是法律挡箭牌而非行为规范了。

The paper (and I only read the abstract) is interesting, but as others have noted, fairly obvious. One thing that seems to be an assumption is that the "company" needs to provide the explanation. I think it is even better if the user provides the explanation. The assumption a user can't provide it is probably because we've all seen Terms of Service agreements that are totally opaque. Back in the day when I was doing a bit of admin work, I decided to simplify our TOS, and then when I had to block someone, I just kicked the ball back into their court: "If you would like your account restored, please point out in the TOS what rule you violated." It worked better than expected. People that cared enough about their access to the system usually figured it out pretty quickly, and we got the knowledge that they actually read the TOS to some degree. They got their account restored and that was the end of it. Repeat offenders at that point were willfully causing problems, so we just left them blocked. Obviously this only works if a human can understand your TOS. Another interesting line of questioning might be "at what complexity level is your TOS useful in shaping behavior and where does it just become a legal shield."
亲历版主亲历：明确告知违反的具体规则能减少冲突，但删帖仍难免招致不满
作为大型 subreddit 的版主，我讨厌删帖，因为会招来围攻。但这就像棒球裁判：规则摆在那里，你违反了公开的规则，我就告诉你违反了哪条。大多数时候不必'驱逐'任何人，但有时不得不。

Moderator of a large sub here. I hate removing content that violates our rules because of the pitch forks coming out. But it's like baseball and you're the ump. These are the rules, you broke the posted rules (and it's not wishy washy rules like /r/politics or /r/videos), and here's the rule you broke. Most of the time you don't have to eject anyone, but sometimes you do.
支持类比线下场景：无解释的纠正令人反感，这是普遍人性
这道理如此显而易见，可惜之前没人研究。它不只在线上有效：让孩子在黑板上解题，然后一声不吭地擦掉他的答案却保留其他孩子的——没人喜欢被不作解释地'纠正'。

It seems so obvious that it's a pitty it wasn't studied before. It doesn't work just online: ask a children to solve some problem in a blackboard and then erase it without telling a thing, while leaving answers from other kids on it. You'll see that nobody likes to be "corrected" without an explanation.
