Estimated survival rate

98%

of 700 recent r/StableDiffusion posts we sampled were still publicly visible about a day later.

How this is measured

Estimate. We sample recent public posts and check again about 18 hours later to count how many are still publicly visible. Posts removed at the moment of submission never become publicly visible at all, so the true removal rate is at least this high. Last sampled Sep 5, 2026.

r/StableDiffusion rules: what actually gets removed

Each rule below is paired with the way it is most likely enforced. Where the rules state a number, we quote it. Where they do not, we say so instead of guessing.

  1. 1.Posts Must Be Open-Source or Local AI image/video/software Related

    Enforcement varies

    Posts must center on open-source/local AI tools (e.g. Stable Diffusion, Flux, PixArt). When relevant you should clearly list tools in the title/body and explain your workflow. Mixed workflows are OK only if they center on the use of local or free tools. Using open tools briefly, then switching to paid/proprietary ones (e.g. SD → Kling) is not allowed. News and comparisons are welcome.

  2. 2.Be Respectful and Follow Reddit's Content Policy

    Enforcement varies

    Respect all artists and users. Constructive critique is welcome, but personal attacks, hate speech, trolling, or bad faith arguments are not. Don’t derail threads or provoke others. Debate ideas respectfully. Bashing AI or non-AI art is not allowed. Follow Reddit’s Content Policy: redditinc.com/policies/content-policy

  3. 3.No X-rated, lewd, or sexually suggestive content

    Enforcement varies

    No nudity, lewdness, or sexually suggestive imagery. If it wouldn’t be appropriate for a workplace or younger audience, don’t post it here. NSFW tags are not an exception, stay classy.

  4. 4.No Gore or Excessive Violence

    Enforcement varies

    Content must be suitable for a general audience. Surreal or eerie imagery is fine, but avoid graphic violence, gore, or shock content. Focus on creativity and storytelling over brutality or horror.

  5. 5.No Politics

    Enforcement varies

    No political figures, imagery, or partisan posts. Legislation or policy discussions related to AI are allowed if relevant, respectful, and on-topic. Don’t post memes or images involving politics, even as jokes. Keep the focus on AI generation and creativity

  6. 6.No Reposts, Spam, Low-Quality, or Excessive Self-Promo

    Enforcement varies

    Don't post just to promote yourself or drive traffic to paid tools, services, or downloads. No paywalls, affiliate links, or hidden URLs. Low-effort posts like images/videos without context or workflows are not allowed. Tutorials and tools must be free and directly accessible. Always search before posting to avoid repeat posts about the same thing.

  7. 7.Use the Correct Flair

    Enforced automatically

    Tag your posts with the correct flair (e.g., News, Tutorial, Workflow). This helps users understand the content at a glance and keeps the subreddit organized. NSFW flair may be auto-applied by Reddit’s systems, but that doesn’t mean it bypasses our rules. Use Flairs appropriately and accurately.

  8. 8.Mod Discretion / Unforeseen Violations

    Removed by moderators

    We can’t predict every possible rule-break. Mods may remove posts or ban users for behavior that clearly violates the spirit of the subreddit, even if it's not covered by an existing rule. This includes things like loophole abuse, coordinated disruption, unexpected spam formats, or new types of low-effort content. This rule exists to protect the community from emerging issues and bad-faith behavior. We’ll use it sparingly and with reason. If in doubt, message the mods before posting

r/StableDiffusion does not publish karma or account-age minimums in its rules. Subreddits often enforce unpublished filters on top of what they write down, which is why posts from new accounts can vanish without a message here.

Can you self-promote in r/StableDiffusion?

No. r/StableDiffusion bans self-promotion outright: product links, launch posts, and thinly framed feedback posts get removed. The sub's own wording: "Don't post just to promote yourself or drive traffic to paid tools, services, or downloads.". If you want eyes on your project, contribute first and look for communities with a promo lane.

What gets removed in r/StableDiffusion

  • Self-promotion

    r/StableDiffusion bans self-promo outright. Product links, launch posts, and thinly framed "feedback" posts are removed.

  • Low karma or a new account

    r/StableDiffusion publishes no karma or age minimum, but unpublished account filters are common at this size. New accounts should comment before posting.

  • Reddit's sitewide spam filter

    A separate layer before the subreddit ever sees your post. New accounts posting links, URL shorteners, and repeated domains are its favorite targets. Removals are instant and silent.

  • A shadowbanned account

    If the account itself is shadowbanned, every post looks live to you and invisible to everyone else, in any subreddit.

r/StableDiffusion posting questions

Can I post links in r/StableDiffusion?

Yes. r/StableDiffusion accepts link posts. The usual sitewide traps still apply: URL shorteners, affiliate parameters, and brand-new domains get filtered fast, and promotional links are judged against the sub's self-promo rules. One clean link to the original source is the safe pattern.

Does r/StableDiffusion require karma to post?

r/StableDiffusion does not publish a karma minimum. That does not mean there is none: many subreddits enforce unpublished karma and account-age filters that remove posts silently. If your account is new or has little karma, that is the first thing to rule out when a post disappears.

Can you self-promote in r/StableDiffusion?

No. r/StableDiffusion bans self-promotion outright: product links, launch posts, and thinly framed feedback posts get removed. The sub's own wording: "Don't post just to promote yourself or drive traffic to paid tools, services, or downloads.". If you want eyes on your project, contribute first and look for communities with a promo lane.

Is r/StableDiffusion strict?

Moderate, by our estimate (24/100 on our strictness scale, from its measured removal rate, 8 rules, and its stated gates). About 2% of recent posts disappeared within a day in our sample. Strictness is about enforcement, not hostility: a strict sub is predictable if you follow its rules.

What is the best time to post in r/StableDiffusion?

Based on our sample of recent and top posts, activity and scores peak around Monday 5am UTC and Tuesday 4am UTC. Treat this as a starting point, not a guarantee: a post that breaks a rule gets removed at any hour. The heatmap on this page converts these windows to your local time.

Why do posts get removed in r/StableDiffusion?

The most common reasons are self-promotion violations, plus the layers every subreddit has: Reddit's sitewide spam filter, unpublished AutoMod rules, and account-level gates like karma and age. In our recent sample, roughly 2% of r/StableDiffusion posts disappeared within about a day of going up. Many removals are silent, so checking your draft first beats finding out after.

Stop getting silently removed.
