Signs of Intelligent Life

For vidders and podficcers here from elsewhere: Space Swap is a multimedia fanworks exchange for all fandoms related to space. We currently allow gift works to be fanfiction, fanart, podfic, fanvids, or interactive fiction.

This is also an event where works must be made by humans, not AI. Currently, the rules simply state that

"AI" works produced using a large language model (such as ChatGPT) or "art generators" (such as Midjourney) are prohibited.

I plan on adding a line that states that works must be produced by the person signing up. Additionally, I want to ban usage of any and all generative AI (so pressing "create vid" on a hypothetical VidGPT is not allowed, for instance). However, as "AI" is the new, trendy way of saying "computer program", and it's possible that e.g. someone's word processor has a spell checker that's built on AI for AI hype reasons, I don't think I can actually blanket ban AI with satisfactory results. Thus, my questions:

1) If I phrase the ban as "By participating, you guarantee that the works produced are made by you alone. Usage of generative AI (for instance, ChatGPT or DALL-E) is strictly prohibited", will people understand this?
2) Are there any other ethical issues related to AI in vidding/podficcing that you would like an official ruling on? I know vidding communities are discussing things like the ethics of AI-based scene extension; I would like to hear about any such discussions going on in the podfic community and also any community consensuses that might have been reached, in addition to discussion and debate.
