Opaque Domain-Level Shadow Banning on Hacker News and Reddit
Users who share links from their own project's domain report those submissions become invisible to logged-out viewers without warning or explanation, a pattern known as domain-level shadow banning on platforms like Hacker News and Reddit. This affects independent builders trying to share their work, who have no formal way to detect or appeal the restriction beyond community "vouch" mechanisms with unclear thresholds. The problem matters because it silently limits organic reach for legitimate builders while offering no transparency into why or how filtering was triggered.

surfaced semanticallyHN post flagging process lacks transparency for submitters
A submitter whose Show HN post was flagged has no clear explanation of why, assuming competitive sabotage. The existing vouching and moderation mechanisms are not well communicated to ordinary users. This is a meta platform discussion with no buildable third-party opportunity.
Hacker News Spam Detection Penalizes Legitimate Project Promotion
A developer finds their project repeatedly flagged or killed by HN's automated spam detection despite genuine community interest. The system conflates repeated legitimate posts with spam behavior. This is a platform-specific moderation edge case with no clear software solution market.
Curiosity About HN Content Moderation Mechanisms
Curiosity about whether Hacker News uses LLM or NLP to detect AI-generated content and deduplicate Show HN posts.
Reddit Login Walls Push Users Toward Alternative Platforms
Users report Reddit increasingly requires login to view content and issues account bans for minor infractions such as VPN use, eroding trust in the open browsing experience. This is driving interest in ad-free, bot-free alternative community platforms.
Indie and Small Sites Are Invisible in AI-Powered Search
Independent websites and small projects are losing discoverability as AI search engines (ChatGPT, Perplexity, Gemini) favor established brands and crawled datasets. No clear mechanism exists for small creators to ensure their content surfaces in AI-generated answers, threatening the long-tail web ecosystem.
