ok, what do you think about an article that was partially written with the help of AI? Or Posts that only have a few snippets produced by ai?

Hi.
I would suggest clearly marking down that text just as you would do with copypasta/quote, and mentioning under/over the text that it is AI-generated.
If would recommend clearly mentioning nin the title of the post that it is AI-generated.
Therefore the reader is aware and no deception about the authorship of writing is created.

For posts [almost]completely written by AI, I would mention it in the title of the post.
