> I don't understand why people are immediately trying to find some loophole in this with spelling, grammar, etc checks.

First, what "loophole" is the comment above referring to? Spell-checking and grammar checking? They seem both common and reasonable to me.

Second, I'm concerned the comment above is uncharitable. (The word 'loophole' is itself a strong tell of that.)

In my view, humanity is at its best when we leverage tools and technology to think better. Let's be careful what policies we put in place. If we insist comments have no "traces of LLM" we might inadvertently lower the quality of discussion.
