What its rules say about promotion
No Spam, No self promotion.
Mod discretion - Posts meant to farm karma or manipulate/harass/scam the community
All 5 rules of r/ProjectHailMary
- No Bullying/Harrassment/Rude
Mod discretion, but we arent going to be policing people like overlords. - No Spam, No self promotion.
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
No piracy links of any kind or discussion on how to illegally obtain video, books, or audio books, of works that should be paid for.
What the written rules don't show
- Unpublished minimums. Many communities remove posts from new or low-karma accounts through AutoModerator settings that are not on the rules page, often before a moderator sees them.
- Reddit's own filters. Reddit's site-wide spam filters can remove posts from accounts that mostly share links to their own site, in any community.
- The community's norms. Many communities see themselves as peers, not an audience: post where you already take part, and make the post worth reading without the link.
Let your AI read the rules before it posts.
ThreadFox reads a community's current rules, writes a post that fits them, posts once with Reddit's Brand affiliate tag and checks it stayed up. The free ThreadFox Lite reads rules too.
