As far as I know using Artificial intelligence to generate content and then post it here is not explicitly against the rules, some users believe it is some kind of plagiarism, while other disagree.
It fits perfectly the definition of plagiarism if you are hiding the fact that you have used AI to create the post. And that's what people will do, either to get merits, sound more knowledgeable, or both. If nutildah created that poll he mentioned, I am sure that a big majority would vote for non-credited AI posts being plagiarism. But a different poll would be more interesting if it had the question,
should AI-written posts be against forum rules and discouraged?
Well, the problem is that using Artificial intelligence to create post is that it widely differs from the classic definition of plagiarism and the way it has been created for most of the history of humanity. You know, until not long ago it implies the copy/pasting and small modification of information which did not belong to us but try to fool others to believe it does. The main problem is the origin of the information, if the AI was legally recognized as an author, then it would easier to accuse someone using it to generate content for their own purposes to be a plagiarist, on the other hand, it would also imply the AI itself is committing massive plagiarism.
I would personally be in favor of restricting the use of AI generated posts in the forum, unless it's origin is explicitly stated and it is used for amusement/experimental purposes. Not to spam around.
