Don't post generated/AI-edited comments. HN is for conversation between humans
TL;DR Highlight
Hacker News officially added a rule banning AI-generated or AI-edited comments — HN discusses what this means and whether it'll work.
Who Should Read
Anyone who participates in online technical communities and cares about the quality of discourse, and developers thinking about AI content moderation.
Core Mechanics
- Hacker News updated its official guidelines to explicitly prohibit comments generated or substantially edited by AI.
- The rule targets both fully AI-generated comments and comments where a human used AI to polish or expand their writing.
- Enforcement is necessarily imperfect — HN can't reliably detect AI-generated text and relies on community flagging and moderator judgment.
- The rationale: AI-generated comments dilute the distinctive HN voice, reduce authentic discourse, and can be produced at scale to manipulate discussion.
- This puts HN in a different posture than most platforms, which have taken a permissive or hands-off approach to AI-assisted content.
Evidence
- The HN guidelines update was linked in the announcement thread, with 'dang' (the main HN moderator) explaining the reasoning.
- Community reaction was mixed: many welcomed it as protecting HN's signal quality, others argued it's unenforceable and draws an arbitrary line.
- Practical debate: is grammar-correcting AI different from spell-check? Where's the line between 'AI assistance' and 'AI generation'?
- Some noted that a skilled human using AI assistance to write a thoughtful comment is probably better for discourse than a careless human writing without it.
How to Apply
- For online community managers: HN's approach of explicit prohibition with community norm enforcement is worth watching — the rule's main value may be establishing a community norm rather than perfect technical enforcement.
- If you use AI to help with writing in online communities, read the specific platform rules — 'AI assistance' policies vary significantly across communities.
- For AI content detection: HN's approach implicitly acknowledges that AI detection tools are unreliable — community judgment and norms may be more effective than technical detection.
