How about inverting the issue, highlight posts with an opt in label. e.g
Show HN [NOAI]:
Since it's too controversial to ban LLM posts, and would be too easy for submitters to omit an [LLM] label... Having an opt in [NOAI] label allows people to highlight their posts, and LLM posts would be easy to flag to disincentivise polluting the label.This wouldn't necessarily need to be a technical change, just an intuitive agreement that posts containing LLM or vibe coded content are not allowed to lie by using the tag, or will be flagged... Then again it could also be used to elevate their rank above other show HN content to give us humanoids some edge if deemed necessary, or a segregated [NOAI] page.
[edit]
The label might need more thought, although "NOAI" is short and intelligible, it might be seen as a bit ironic to have to add a tag containing "AI" into your title. [HUMAN]?
Is the problem that the app was written with AI assistance or that it's low-effort/bad? I don't care if you used Claude to fix a bug or something if you have a cool app, but i do care if you vibe coded something I could've vibe coded in an hour. That's boring.
Feels like effort needs to be the barrier (which unfortunately needs human review), not "AI or not". In lieu of that, 100 karma or account minimum age to post something as Show HN might be a dumb way to do it (to give you enough time to have read other people's so you understand the vibe).
A core part of the HN ethos is avoiding siloing dynamics, which is exactly what [NOAI] would be.
I'm 90% sure this will end with endless squabbles who's right that the label is correct/incorrect, rather than actual conversations about what the project that the person is showing. It already happens without the labels, feels like it'd increase the frequency of that even more if this label gets enforced.
