As long as you admit that particular text is machine-generated, I see nothing wrong in publishing and reading such text.
Yes. I think that's important. It's good to know the background of the author. If the author is reluctant to discuss their background, then they must be worried about their safety. For the time being, we can assume it's political pressure. But some day in the not too distant future, we will have to consider that an anonymous, unverified author might be on the wrong side of politics, is AI, or both.
That's right, unfortunately.
That's one of the reason's I'm publishing my autobiography online, daily, all over the place.
