Subreddit rules check

Can you promote here?
Promotion is allowed only with moderator permission (or inside designated threads). A short, honest modmail before posting costs two minutes and functions as a safe-conduct pass; skipping it is the most common avoidable removal.
From the rules · Self-promotion appears tolerated in designated/limited ways (users mention “self promotion Saturdays”); moderators remove low-effort/link-only posts and expect substantive commentary.
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: discussion, showcase, question
Headline: short, first-person or question (e.g., “Just finished X”, “Has anyone read…”, “My art from August”). Write in first person; 1–3 short paragraphs. Tone: casual, enthusiastic, nerdy. What wins: genuine takes, added commentary, images or thoughtful questions. What gets removed/downvoted: link-only posts, bare promo, or posts with no substantive comment.
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 September 2026. Rules change and moderators have the final say: verify at r/scifi'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.
