Hacker News 未公开功能与行为清单（2018）
A List of Hacker News's Undocumented Features and Behaviors (2018)
2019 — 2025，它一次次回到首页
黑点是上首页（≥ 50 分）的那次投稿，空心点是没冲上去的投稿，点越大分数越高。
导读
这是数据科学家 Max Woolf 整理的 Hacker News 未公开功能与行为清单，涵盖投票机制、排名算法、账号惩罚等社区运作细节。它多次登上 HN 首页，成为了解这个社区幕后规则的经典参考。
为什么经久不衰：HN 的界面几十年不变，但其内部规则鲜有官方文档，这份社区自发整理的清单填补了空白，且随时间不断被验证和补充。
HN 评论精选
HN 克制不加功能本身就是它最大的优点
对我来说 HN 最大的特色就是没有特色——没有'创新'，或者说没有为了改版而改版的重设计。感谢 HN 团队出色的管理和对创新的'拒绝'！

To me HNs biggest feature is the lack of features and the lack of 'innovation', or rather redesigns for the sake of redesigning. Keep up the fantastic moderation and the wonderful lack of innovation, HN people!
被标记的账号会进入隐性惩罚模式，投票权重不再正常计算
我来补充一条：账号可能被切换到不同的 karma 计算模式，也就是说一次 downvote 不总是等权重的 downvote。因发布煽动性或意识形态化评论被标记的账号，会被切换到另一种投票模式：手动 downvote 权重更高、upvote 被低估，或随时间自动施加一种需要克服的'下沉引力'。我因一些过于好斗的 COVID 相关评论被标记，连有理有据的技术评论也难免掉到 -1。联系 dang 后他确认了我的账号被机器人 downvote，同时解释账号确实被标记了，并指出了越界的帖子。

I’ll add one to this list, I’m sorry if it comes off as complaining, but at least it’s topical. There is more than one karma tracking algorithm that can be activated for a given account. That is to say, a downvote is not always a downvote, and an upvote is not always an upvote, and the point score of a comment is not always exactly equal to the number of up and downvotes. Accounts that are flagged for posting flame-baiting or ideological comments can be switched to an alternate voting mode where votes are not counted the same way. This may mean that any manual downvotes are given greater weight, or upvotes are underweighted, or downvoting is automatically applied after some time providing a type of downward gravity which must be overcome. I don’t know the precise algorithm. It’s complicated by the fact that I’ve been getting auto-downvoted by bots. But due to some overly combative COVID related posts my account is in this current state. I’ve found that even researched technical comments of mine will inevitably end up at -1 karma, or struggle to stay above 0. After reaching out to dang about bot-downvoting Daniel was nice enough to look into it and confirmed my account was getting bot-downvoted but also explained that my account had been flagged and made some suggestions on posts that crossed the line. I’ve had a long and mostly enjoyable relationship with HN so hopefully I’ll be out of purgatory soon. To be clear I have no interest in debating whether the feature was misapplied in my own personal case, but rather just it’s abstract technical merits make for great meta-discussion of moderation techniques for social media boards.
HN 会静默过滤标题中的 emoji 和感叹号等字符
我觉得清单还漏了一些'功能'：HN 会悄悄删除标题中的某些字符（比如 emoji 和感叹号），这在我看来是个糟糕的特性，大家应该知道。

I think there are some "features" missing from this list. I seem to recall that Hacker News will transparently remove some characters from titles (such as emoji and exclamation points), which seems like a bad feature to me, and one that people should be aware of.
/invited 页面收录了早期高质量帖子，值得一逛
哦，我以前不知道 /invited 这个页面。里面有一些质量很高的帖子，看起来像早年的 HN。
