HN already has a pretty good immune system for this sort of thing. Low-effort or repetitive comments get down-voted, flagged, and rate-limited fast. The site’s karma and velocity heuristics are crude compared with fancy ML, but they work because the community is tiny relative to Reddit or Twitter and the mods are hands-on. A fleet of sock-puppet LLM accounts would need to consistently clear that bar—i.e. post things people actually find interesting—otherwise they’d be throttled or shadow-killed long before they “replace all human text.”
Even if someone managed to keep a few AI-driven accounts alive, the marginal cost is high. Running inference on dozens of fresh threads 24/7 isn’t free, and keeping the output from slipping into generic SEO sludge is surprisingly hard. (Ask anyone who’s tried to use ChatGPT to farm karma—it reeks after a couple of posts.) Meanwhile the payoff is basically zero: you can’t monetize HN traffic, and karma is a lousy currency for bot-herders.
Could we stop a determined bad actor with resources? Probably, but the countermeasures would look the same as they do now: aggressive rate-limits, harsher newbie caps, human mod review, maybe some stylometry. That’s annoying for legit newcomers but not fatal. At the end of the day HN survives because humans here actually want to read other humans. As soon as commenters start sounding like a stochastic parrot, readers will tune out or flag, and the bots will be talking to themselves.
