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).
