## Nauti's Take

HN quietly filtering AI-generated content without ever announcing it fits the platform's philosophy perfectly: tune in the background, avoid the meta-debate. The irony is sharp – a community that obsessively discusses AI apparently wants humans-only input. Whether the detection relies on an actual LLM or simple heuristics, nobody outside YC knows. Without transparency, that is a credibility gap, not a feature.
