alt Hacker NewsI think all your examples are all perfectly fine.
As for expansion, that might just be the risk we take. I been downvoted on reddit for being "too verbose" in my replies and I'm a human. And perhaps just reading the prompt in that case wouldn't give you more information; the LLM might actually have some insight that is relevant to the conversation. What's the difference between that and googling for something and pasting it in?
The linked rule does not make such a distinction, and I don't see how this rule could be enforced with such a caveat, either.
Hence no, none of these examples should be okay. Even if pure translation and grammar check is gonna be effectively impossible to detect too, so likely pointless to talk about
And the last one is often detectable and very clearly against it - I'm not sure how you can come to any other conclusion
