Subreddit rules check
r/mystery
Can you promote here?
The written rules take no clear position, which is NOT permission: unclear communities enforce norms through removals instead of rulebooks. Sort by top, study which builder posts survived and how they were framed, and when in doubt ask the mods.
Links
The rules clearly allow links. A plain-text mention still often outperforms a URL from a young account.
What this community rewards
Dominant post formats: story, discussion, question
Headline: short case name + year/location or a direct question. Write mostly in third-person factual summaries for case posts; use first-person for personal/household mysteries. Typical length: medium (several paragraphs). Tone: sober, investigative, respectful. Upvotes reward thorough, sourced timelines and unanswered cases; avoid sensationalism, unverifiable accusations, or speculation presented as fact.
Arriving in the local format matters: cross-posting the same text everywhere reads as tourist instantly. The wider method is in the Reddit playbook.
Classified mechanically from the community's published rules and recent top posts, last checked October 2026. Rules change and moderators have the final say: verify at r/mystery's rules page before posting anything that matters.
Thread Otter checks this before every send
These profiles power the product: promo-banned communities never receive a promotional draft, drafts arrive in the local format, and a fact-check gate plus human pacing protect the account doing the talking.
