Subreddit Rules
- Be Respectful: Treat others kindly. Debate the ideas, not people. We will not tolerate harassment, hate speech, or personal attacks. If you disagree with someone then explain your thinking in a civilized manner. No racism, sexism, homophobia, transphobia, or other forms of discrimination.
- Science fiction is about exploring diverse possibilities and perspectives. Let that spirit guide your interactions here.
- Sci-Fi Only: **Posts must include a science fiction element.**
- This subreddit is for **science fiction**. Fantasy is welcome *only* when it includes *scientific* or *technological* aspects.
- For example, *Star Wars* features mystical elements like the Force, but also spaceships and advanced technology.
- No AI-Generated or AI-Assisted Content: **AI artwork, writing, or media are not permitted** — even if partially created or edited using AI tools.
- This includes **AI text generators**, **image models**, **voice synthesis**, or any other **automated creative process**.
- Discussion of **AI as a topic in science fiction** is welcome — posting **AI-produced creations** is not.
- Self-Promotion/Original Content: Did you write it, build it, draw it, code it, photograph it, film it, or otherwise create it? Do you own or run the website you're promoting?
- Note: we do not allow referral links, direct selling, crowdfunding links etc. Do not recommend your books, website, products, or other self-promotional content in the comments outside of this day.
- Share your original sci-fi work on Saturdays only. Midnight to 2359 (CST).
- Quality Matters: Low-effort posts (memes, spam, karma farming, posts with no context) will be removed. Text posts shorter than 250 characters will be auto-removed.
- Original media that is not your own work is welcome. Please credit the creator and title. Explain why you are sharing the image/video/article etc. "It's cool" is not a valid reason.
- Use informative titles and avoid clickbait.
- Reliable Sources: Sharing a link? Please use trustworthy and original sources only.
- Avoid sites that just repackage press releases or steal content for ad and affiliate clicks. These may be removed.
- We also do not want people, sharing crowdfunding websites, asking for donations etc. Posts and comments with these will be deleted.
- English Only: To keep discussions accessible to everyone, please post in English.
- Posts about foreign-language books, films, or shows are welcome — but the post title and body should be written in English so all members can participate in the conversation.
- Comments in other languages are allowed, but English is preferred so the broader community can follow along.
- Use correct post flair: Use the correct **flair** for your submission:
- | **Flair** | **Description** | |------------|----------------| | **OC (for SPS)** | Original content — weekends only | | **ID This** | help remembering titles | | **Recommendations** | Looking for sci-fi suggestions | | **TV / Films / Games / Print / Art** | Pick your medium | | **Community** | Meta posts, rules, or subreddit discussions | | **General** | Everything else that fits the rules |
- Search Before Posting: **Contribute with care.** Before posting, check if the topic has already been shared recently. Posts on the same subject within the past **7 days** may be removed.
- Be curious, constructive, and help make r/scifi a hub for exploration, creativity, and discovery.
- No NSFW Content: Keep r/scifi **safe for all audiences**. NSFW or sexually explicit material is not allowed.
- There are other subreddits for that kind of content — please share it there instead.
- No Spoilers!: Use spoiler tags when discussing any major plot detail, twist, or ending, even for older works.
- Format: `>!spoiler text!<`
- • No spoilers in titles or images. Titles should remain spoiler-free at all times. • If your post's body contains spoilers, format them as such or add "[SPOILERS]" to the title. • When in doubt, tag it.
