I only have one answer for you, unfortunately:
Currently, we do have a company stated guideline here. It’s also mentioned here in the recent thread about the withdrawn game.
Whether that’s the “right” thing, or the thing the company will stick with, that’s the only definitive thing that I know of to answer your question. I also know staff encourages writers to reach out to them directly via email with questions.
As for how they will handle detecting it, discerning AI content from human content, who or how they are making those choices… I can’t pretend to know. The reason I personally think it is better to privately discuss any concerns about a writer’s work is because, as I’ve said here and elsewhere, I think the accusation is too damaging and shouldn’t be made publicly until the company has taken a stance on the particular case. Public opinion is rarely the right way to tackle the issue of a person’s guilt and even less often the right way to tackle the issue of their redemption. But I’m not staff so my opinion isn’t really relevant, just an opinion.
Please don’t do this. Mara has made it clear that she doesn’t want to be involved right now and you can share your opinion without directly going at her or dismissing her feelings. I’m not not trying to come at you or deny you the right to share here, but let’s not antagonize each other. We can all say what we want to say without being so harsh.
