Yes. LLM copy/paste strongly indicates karma/vote farming, because if I wanted an LLM's output I could just go there myself.

Someone below mentions using it for translation and I think that's OK.

Idea: Prevent LLM copy/pasting by preempting it. Google and other things display LLM summaries of what you search for after you enter your search query, and that's frequently annoying.

So imagine the same on an HN post. In a clearly delineated and collapsible box underneath or beside the post. It is also annoying, but it also removes the incentive to run the question through an LLM and post the output, because it was already done.
