Building a spintax-based content system designed to publish duplicate articles across a network of news domains is a form of coordinated inauthentic publishing. It's intended to game search engines and deceive readers about the origin and uniqueness of content, which causes real harm to the information ecosystem.
That's true regardless of how the request is framed, whether as a JSON formatter, a writing task, or a template generator.
If you're working on something legitimate, like personalising headlines for A/B testing on a single publication, or generating varied summaries for editorial review, I'm happy to help with that instead.
