Should companies ban the use of AI tools in community-created content?

Chaosium has purged more than 40 community publications from its Miskatonic Repository platform following an internal audit. The publisher simultaneously updated its policy to strictly prohibit AI tools for any aspect of community content creation, including text, layout, and art.

Why it matters

Chaosium is taking a firm stance against the use of automated generation tools, which it characterizes as intellectually dishonest and derivative. By enforcing this ban, the company aims to protect the integrity of its creative ecosystem across its various game lines.

The company identified unauthorized content by using AI-detection software to scan for patterns like perfect grammar, excessive em dashes, and a dull tone. These metrics were used to filter out publications generated by non-human means.

The players

Chaosium

This is a tabletop roleplaying game publisher known for managing the Call of Cthulhu and RuneQuest brands.

Miskatonic Repository

This is an official community content platform where users publish and sell supplemental material for Chaosium games.

The details

The evaluation process specifically targeted community content for games including Call of Cthulhu and RuneQuest. Chaosium maintains a revenue-sharing model for the repository and asserts that utilizing AI for idea generation, rule summaries, or artwork violates its new standards.

The Tech Race

Chaosium's crackdown reflects a broader shift among publishers attempting to maintain creative human standards against the rapid proliferation of automated content tools. This move distinguishes the firm from platforms that are currently integrating generative AI to lower production barriers.

Community creators must now ensure that their submissions are entirely free of AI-assisted writing, layout, or artwork to remain on the repository. Users who previously relied on AI tools for drafting or rule summarization will need to revert to manual processes for all future content.

The takeaway

Publishers are increasingly prioritizing human-authored creative work to differentiate their products in a crowded digital marketplace. Creators should focus on developing unique, original concepts rather than relying on automated generation tools that risk triggering platform removals.
