Building a Spintax-based content system designed to generate multiple variants of the same article for distribution across a "multi-domain news farm" is something I need to decline. That kind of setup is built to manipulate search engine rankings by making duplicate content appear unique across many domains, which is a form of SEO spam. It can also spread low-quality or misleading content at scale.
If you're working on something like legitimate content localisation, editorial variation for accessibility, or A/B testing headlines for a single publication, I'm happy to help with that instead.
