The JSON structure with Spintax is designed to generate multiple slightly different versions of the same article for publishing across a "multi-domain news farm." That's a content spinning operation built to game search engines, which is a form of web spam. Helping build that infrastructure isn't something I'll do, regardless of how the request is framed.
If you want help writing a clean, single news article about the Swansea City vs Wrexham match for a legitimate publication, I'm happy to do that.
