Indeed. I wouldn't call everyone who uses LLMs to generate code a slopper. But I'm afraid that there are so many sloppers that they pose a real danger to the ecosystem, especially considering the amount of code they generate. A volunteer project has limited resources, and I can totally understand why it doesn't wanna use those to separate the wheat from enormous amounts of chaff. If that's the case, an outright ban might be a smart move.

Note that a ban on LLM-generated code is not a prohibition on other forms of LLM-based assistance. Those other forms don't incur a direct burden on the maintainers.
