This is going to be a tough ask. I am with this 100% for "ai generated" but not "ai edited". What if I'm using AI for spellchecking or correcting bad grammar? what if it is an accessiblity-related use case? or translation?

It's just a tool ffs! there are many issues with LLM abuse, but this sort of over-compensation is exactly the sort of stuff that makes it hard to get abuse under control.

You're still talking with a human!, there is no actual "AI" you're not talking to an actual artificial intelligence. "don't message me unless you've written it with ink, on papyrus". There is a world of difference between grammarly and an autonomous agent creating comments on its own. Specifics, context, and nuance matter.
