While myself and my producer use AI, we disclose our AI use, so those who don't care for AI can do it themselves, give it to us, and we could replace the AI genned stuff with the human-made stuff (of course, properly credited for the volunteer work).
My producer, Neigsendoig, was always willing to let people draw out exactly what he generates.
In particular, CoculesNation and Cocules Reddit Readings have AI-generated photos we generate and use ourselves in some thumbnails.
No, it's fully human. I'm an author (I actually did a FediWriMo last month, in fact), and this is just how I write, no matter how long the responses are.
I guess you could tell my PFP is AI-generated, of which it is (It's indeed mentioned in my bio).
