What you're describing is a content spinning system for a "multi-domain news farm," which is infrastructure for generating and distributing near-duplicate content across multiple domains. That's a form of coordinated inauthentic publishing designed to manipulate search rankings and deceive readers about the origin and uniqueness of content.
That applies regardless of how the request is framed, including as a JSON formatting task or a writing exercise.
If you're working on something legitimate, like summarizing news for a single publication, formatting articles for a CMS, or writing clear explainers on cost-of-living topics, I'm glad to help with that.
