Some people already dismiss genuinely useful content solely based on the use of AI to assist in writing it - i am not sure what flagging would do other than to reinforce that prejudice.
I posted a couple of my articles here, and the one that got traction was generally well received (and also received some constructive feedback from those who acknowledged that is was AI assisted) - but it is evident across HN there is a vocal minority who outright dismiss content solely because it was "AI generated" completely disregarding the content itself. I appreciate this is personal taste, or LLM fatigue, or whatever, but its not really constructive.
If what you want to do is target the slop while not targeting the quality content, then that is what the voting mechanism already does. If people don't like something they can downvote it. Flagging content as AI generated is just a dogwhistle to those who want to downvote AI generated content. If anything, id rather see a rule that stops people commenting on stuff just to dismiss it as "LLM slop".
Its already trivial to avoid detection with fine-tuned humanisers [i] built on non-instruction-tuned models. That makes the flag mostly useless - or worse - a way of penalising any content you disagree with. I'd rather not hide what I am doing and have something that I feel reads well than hide it and sacrifice the message to satisfy a vocal minority.

EDIT: downvotes, as expected. hope you see this anyway @dang. Downvotes kind of make my point for me.
Why is that a good thing? If you aren't going to bother to write something, other people shouldn't have to bother to read it, so please don't put it in the world at all.
Gatekeeping based on skill and motivation is good!
So why are you doing that by sloppyfying your own writing? If you want people to take interest in your writing, it should probably actually be your own writing.
