You should really worry less about it. The ruling is really more about the fairly blatantly obvious cases. If people want to feel rebellious and try to have the AI write the content in such a way that it is hard to distinguish, that's good on them. As long as the AI-generated content isn't equally as bad and soulless as any other low-effort posting, you don't need to be worried at all. Whether people want to flex about replacing genuine effort with genuine-looking effort, though, is really their own issue.
