It seems silly, but I have something similar on my sites now. Are there any better options?

My content is under a license, the terms of which already explicilty prohibits training LLMs on them. I'm not under the delusion that this alone is going to stop any of the criminal GenAI companies from doing it anyway. Yet I still put an additional sentence like this just because, as someone with no particular legal experience, it makes me feel like I'd had a better argument if I ever decided to sue someone about it for kicks. I think it should make it more difficult for any GenAI company to claim that they couldn't have known what the terms were when they accessed the content.
