The mods have put together some language, given recent direction from SE:
> We, the moderators, understand that this community has no interest in hosting AI-generated posts. Unfortunately [MSE policy link] directs that we may not delete posts based on suspicion of AI provenance, unless that source is *freely* offered by a post author. Furthermore, we may not suspend users for repeatedly posting suspected AI-generated content.
> You, of course, are free to act in any manner that hews to the [Code of Conduct].
