But I think the harder part is that enforcement depends on detection, and detection will always lag generation..
I can see some beneficial purpose for almost all forms of AI, but allowing AI generated reviews (for anything) is a perversion of the concept of a review for humans. Besides, you know 1000% AI reviews are going to be gamed and steered by humans running the operation for profit, so it's not really an AI review anyway, it's just ai-washed human fraud.
The day I will accept AI reviews is the day we declare AIs to have human rights and responsibilities. Until then it's just slop and/or lies, depending on how charitable we're being.
