It is enforceable, I think you mean to say that it cannot be prevented since people can attempt to hide their usage? Most rules and laws are like that, you proscribe some behavior but that doesn't prevent people from doing it. Therefore you typically need to also define punishments:

> This policy is not open to discussion, any content submitted that is clearly labelled as LLM-generated (including issues, merge requests, and merge request descriptions) will be immediately closed, and any attempt to bypass this policy will result in a ban from the project.

I suspect this is for now just a rough filter to remove the lowest effort PRs. It likely will not be enough for long, though, so I suspect we will see default deny policies soon enough, and various different approaches to screening potential contributors.

Any sufficiently advanced LLM-slop will be indistinguishable from regular human-slop. But that’s what they are after.

This heuristic lets the project flag problematic slop with minimal investment avoiding the cost issues with reviewing low-quality low-effort high-volume contributions, which should be near ideal.

Much like banning pornography on an artistic photo site, the perfect application on the borderline of the rule is far less important than filtering power “I know it when I see it” provides to the standard case. Plus, smut peddlers aren’t likely to set an OpenClaw bot-agent swarm loose arguing the point with you for days then posting blogs and medium articles attacking you personally for “discrimination”.

Probably just an attempt to stop low effort LLM copy pasta.

> The LLM ban is unenforceable

Just require that the CLA/Certificate of Origin statement be printed out, signed, and mailed with an envelope and stamp, where besides attesting that they appropriately license their contributions ((A)GPL, BSD, MIT, or whatever) and have the authority to do so, that they also attest that they haven't used any LLMs for their contributions. This will strongly deter direct LLM usage. Indirect usage, where people whip up LLM-generated PoCs that they then rewrite, will still probably go on, and go on without detection, but that's less objectionable morally (and legally) than trying to directly commit LLM code.

As an aside, I've noticed a huge drop off in license literacy amongst developers, as well as respect for the license choices of other developers/projects. I can't tell if LLMs caused this, but there's a noticeable difference from the way things were 10 years ago.
