Why do you stubbornly refuse to accept the fact that AI has been here and will be here? Yes, there is a hunt for them now, but AI is getting better every day. You say that AI spammers will definitely be caught. Yes, it is possible, but let the one who catches speak and not the one who talks... You just conclude with very pretentious thoughts that punishment is inevitable, but you know what? The one who does this, the one who uses AI, is just laughing, because he probably doesn't care about trust, which he doesn't value, or reputation, since greed primarily owns him. You can give as many examples as you want with Ratimov, but people post with AI for completely different purposes. I'm telling you as someone who sees the syllable of AI but cannot prove anything, since detectors can no longer accurately determine the use of this instrument unambiguously.
Whatever you said is true, the ones who know how to trick AI detectors don't really care much about the ethics, or about their reputation, they mainly use AI to increase the number of their posts because their main intention is to earn more money with multiple accounts without getting caught.
Even, if one of their accounts is caught, they can use other accounts for the purpose. AI is getting better at producing human level text with emotions, and the days aren't far when all of the detectors will fail to detect any AI generated content. The ones who're good at using AI LLMs can tweak current models to produce text that sounds genuine and human written.
I agree with Philipma1957 that no matter what we do, the forum will still have AI content but hide in shadow so the detectors might not be able to know but it'll indeed be AI written text.
