@lcamtuf Only half? Seriously, I'd tweak your #1 to make it less dependent on detecting LLM writing [1] and alter the condition to include quality [2]. If the writing is well written AND makes a good point I'd say it's worthwhile.
I doubt there's much of this at all today, but why would it be so bad if it became a thing?
NOTES: [1] this isn't easy to detect accurate by software (and will get harder) and manually time consuming, plus false positives would be a loss.
[2] Low quality writing (LLM of human) is best avoided and can be detected quickly and accurately.
