of 20 recent r/startup 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 Oct 10, 2026.

r/startup 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.

    No spam meant to drive traffic off-site. No solicitation/

  3. 3.Self posts only (Enforced)

    Enforcement varies

r/startup 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 Subreddits often enforce unpublished filters on top of what they write down, which is why posts from new accounts can vanish without a message here.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/startup?

No. r/startup bans self-promotion outright: product links, launch posts, and thinly framed feedback posts get removed. The sub's own wording: "No spam. No Solicitations: No spam meant to drive traffic off-site. No solicitation/". If you want eyes on your project, contribute first and look for communities with a promo lane.

What gets removed in r/startup

  • Self-promotion

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

  • Low karma or a new account

    r/startup publishes no karma or age minimum, but unpublished account filters are common at this size.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/startup posting questions

Can I post links in r/startup?

No. r/startup accepts text posts only, so a link-only submission is rejected at the door. You can usually mention a link inside the body text, but the sub's rules on self-promotion still apply to it. Check your draft against the rules before posting.

Does r/startup require karma to post?

r/startup 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 That does not mean there is none: many subreddits enforce unpublished karma and account-age filters that remove posts silently.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.

Is r/startup strict?

Relaxed, by our estimate (18/100 on our strictness scale, from its measured removal rate, 3 rules, and its stated gates). About 0% 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.

Why do posts get removed in r/startup?

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 0% of r/startup posts disappeared within about a day of going up. Many removals are silent, so checking your draft first beats finding out after.
