Subreddit Rules
- No Bullying/Harrassment/Rude: Mod discretion, but we arent going to be policing people like overlords.
- No Spam: Mod discretion - Posts meant to farm karma or manipulate/harass/scam the community
- No external links for purchases.: Given the litany of spam posts with links meant to scam people, we are formalizing a no-link for any kind of purchases rule.
- An acceptable example of what would be allowed is, "if you'd like to buy the Project Hail Mary audio book, you can locate it on Audible. You'd need to Google it since links aren't allowed."
- No T-shirt Posts: The primary scam route we have seen is for scammers to post an image of a t-shirt and then post a scam link within.
- There has only been one legitimate t-shirt post I have seen, so the impact should be minimal for the community.
- No Piracy Links or Discussion
- piracy links of any kind or discussion on how to illegally obtain video, books, or audio books, of works that should be paid for.
