I was about to disagree, but that’s actually really interesting. Could you expand on that?
If you want to lie without getting caught, your public submission should have neither the hallucinations nor stylistic issues associated with "made by AI". To do so, you need to consistently review the output of the generator (LLM, diffusion model, etc.) and manually fix it.
In other words, to lie without getting caught you're getting rid of what makes the output problematic on first place. The problem was never people using AI to do the "heavy lifting" to increase their productivity by 50%; it was instead people increasing the output by 900%, and submitting ten really shitty pics or paragraphs, that look a lot like someone else's, instead of a decent and original one. Those are the ones who'd get caught, because they're doing what you called "dumb" (and I agree) - not proof-reading their output.
Regarding code, from your other comment: note that some Linux and *BSD distributions banned AI submissions, like Gentoo and NetBSD. I believe it to be the same deal as news or art.
