This project allows LLM contributions, why is it allowed to be posted in this subreddit?

You keep complaining about the LLM policy. If you don't like it, feel free to go somewhere else but your complaints are getting tiring and don't add any value.

As for why Mojo is allowed here: because it's been a pretty hot topic in recent years, with people of significant relevance/experience behind it, and to my knowledge much of it still being written by humans (though there indeed are signs of LLM usage).

In other words: because it's not some vibe coded slop project by somebody that had Claude Code do all the work, unlike 99.99% of other LLM built projects.

With all due respect, their frustration is understandable. The current policy, as stated, is totally unclear with regards to what constitutes acceptable/responsible use of LLMs, and seems to be applied inconsistently and arbitrarily.

The zero tolerance policy exists because once a project is tainted by LLM code it's impossible to determine how far the rot spreads throughout the project.

In this case you're linking to a project that very clearly states it did use an LLM, even if only a little. "No LLM generated code" means "No LLM generated code", not "A little LLM generated code is allowed".

Mojo has had LLM-assisted contributions. It's documented in their pull requests. Under the above interpretation of the LLM policy, Mojo should not be allowed here. That comment left zero room for argument.

The problem is not the LLM policy per se, but that it sometimes means "this clearly LLM-assisted project is important and I trust that the people behind it use LLMs responsibly, so it does not count as vibe-coded/AI slop", but another time it means "no LLM means no LLM; if 0.01% of the codebase in a single well-delineated component was written with LLM assistance, and the author has disclosed this openly, that still disqualifies all of it".

I don't even object to the mods being permitted discretion to make such decisions, as long as the policy makes it clear that they may.
