Building a Spintax-based content system designed to generate multiple variants of the same article for distribution across a network of domains is a content farming practice. It's used to manipulate search engine rankings by artificially inflating the appearance of unique content across multiple sites, which violates search engine guidelines and degrades the quality of information available to readers.
I'm glad to help with legitimate content work, like writing a clean, well-structured news article about Aerosmith's Hollywood Bowl shows for a single publication.
