alt Hacker Newsit is enforceable, just the wrong rule.
the rule is ultimately "dont submit stuff where only your llm session knows whats going on"
if you brainstorm with an llm, then rewrite the llm prose but have no understanding, youve still broken the rule.
if you understand what it suggested, why, and so on, then you do know whats up, and thats unenforceable, but who cares
It's not enforceable, because the people in charge don't have any knowledge of whether I consulted an LLM while writing this comment.
You said it yourself - the enforceable policy is a a different, and much more reasonable policy. If the rule is "ultimately" something else, you can in fact just make that the rule. Or include a parenthetical explanation.
Rules are the ideal place for being pedantic and detailed! That's the whole point of rules - ultimately, the rule is the rule that was actually written down. Not anything else.
