Subreddit Rules
- Keep things civil: We have zero tolerance to harassment and discrimination, and hateful ideologies and/or behaviours are not welcome in this community. This includes abuse, harassment, frivolous and false accusations, and discrimination (particularly on the basis of race, creed, sex, sexual orientation, gender expression, or physical or mental ability).
- Additionally, we want to foster an environment for productive and helpful discussion, and as such personal attacks are not appropriate.
- Stay on topic.: Discussion topics for this subreddit should specifically be about the Call of Cthulhu roleplaying game by Chaosium. There are more appropriate subreddits for general Lovecraftian topics, such as r/lovecraft, and more general tabletop roleplaying topics, such as r/rpg.
- The requirements for "relevance" for AI-produced-content are higher than for that created by an artist or author, and these can be found here: https://www.reddit.com/r/callofcthulhu/comments/10yp0vw/mod_update_ai_art/
- Use appropriate post flair: There are hundreds of potential music tracks, artworks, battlemaps, props, videos and other such general resources that can be utilised as tools by keepers and enjoyed by players. These resources are a valuable contribution to the community, however, can quickly clutter and dominate the subreddit when shared through separate posts. All such content is to be only shared in the provided ‘Keeper Resource Mega-thread’ found at the top the subreddit.
- Use proper spoiler tags and markup for all published scenario and campaign spoilers.: Users with different levels of experience are welcome here, and as such it is common courtesy to ensure that spoilers are properly tagged.
- No memes: r/callofcthulhu is a bastion of high-quality content and discussion about Chaosiums Call of Cthulhu. To ensure the ongoing quality and integrity of the subreddits, memes will be removed.
- No advocating piracy.: We have a zero-tolerance policy towards piracy, including the sharing of pirated material or asking for pirated material, either directly or indirectly.
- Self-promotion guidelines: We support community content creators, and as such wish to make the community available for people to promote their creations, podcasts or other content that directly relates to Chaosiums Call of Cthulhu. However, we do not wish to see the subreddit overtaken by self-promotion posts, as such we ask that you limit self promotion posts to a maximum of one per month.
- Images should be directly relevant to Call of Cthulhu the TTRPG.: This can include artwork you have produced for your game, art of your characters etc. It does not include images you have found online or made that are just lovecraftian or of monsters. Please make it clear in the post title how your art specifically relates to the game. Additionally, we have a higher benchmark for AI-Generated art. More information can be found here: https://www.reddit.com/r/callofcthulhu/comments/yy117a/mod_post_rules_clarification_for_aigenerated_art/
- No affiliate links: This subreddit is a community of people who share a common interest, and whilst we encourage authors etc to share their work here, we do not allow affiliate links.
- No AI-generated content or discussion of the use of AI: Enquiring whether AI was used during the creation of something is allowed. Please do not outright accuse someone of generating something with AI without EXTREMELY comprehensive proof. If someone responds to your question stating that AI is categorically not used in the creation of the work they have shared, that is the end of the discussion. Further scepticism or disbelief will be removed.
