User blog comment:FluffyYoshi/Wikia is Selling Our Articles/@comment-1827503-20161024203051

Survivor Wiki uses the CC-BY-SA license, which requires attribution. We cannot prove that attribution was not given (unless someone actually buys the book), so we cannot prove the license was violated.

Wikia had nothing to do with this, beyond the articles being hosted on their own site. Under United States law, they are not responsible for user-created content per Section 230 of the Communications Decency Act.
