What was that new benchmark recently that no LLM could pass? Pull it up, wrap into a captcha service, apply for a YC funding round.
The very few humans on the planet able to solve this will be blocked and will have to use another manual process that would slow them but every LLM would successfully fail.
Which is against the rules, that you chose to not read?

Further, the guidelines have long stated not to use HN primarily for self promotion. First, try being part of the community and understanding how things work here. Coming here to "accomplish" showing off your project is faux pas.
The fact is the ethos of this forum has become antithetical to what hacker culture and tech have become, which is incurious, misanthropic and aggressively pro AI. That isn't a problem that can be solved with engineering, it's existential. Either the culture changes or HN does, and as HN's whole thing is "avoiding the Eternal September at all costs," which reduces to "avoiding cultural change at all cost," HN can't change and survive. Immovable object versus irresistable force.
I guess the only advice I have is to stop using HN whenever it becomes useless to you and find greener pastures. The Fediverse is still good.
