Estimated survival rate

94%

of 85 recent r/javascript 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/javascript 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.Excessive Self-Promotion

    Enforcement varies

    It's ok to promote your own content, or content that you're otherwise vested in, but it should not constitute a majority of your contributions.

  2. 2.Where's the Javascript?

    Enforcement varies

    Demos can be fun, but they really don't provide for much discussion unless code is provided as well.

  3. 3./r/JavaScript is not a support forum

    Enforcement varies

    Is this a help request? Try /r/LearnJavascript instead!

  4. 4.Java !== Javascript

    Enforcement varies

    Java is not the same as Javascript.

  5. 5."Remember the human."

    Enforcement varies

    "Remember the human." It's ok to disagree, but we should attack ideas, not people.

  6. 6.Low-effort content (listicles, memes, etc.)

    Enforcement varies

    Low-effort content such as listicles, memes, clickbait, etc. is prohibited.

  7. 7.Advertising

    Enforcement varies

    Advertising paid products and services is prohibited.

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 Subreddits often enforce unpublished filters on top of what they write down, which is why posts from new accounts can vanish without a message here.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

Yes, within reason. r/javascript allows self-promotion, but Reddit's sitewide 9-to-1 guideline still applies: accounts that mostly post their own links get filtered as spam regardless of sub rules. The sub's own wording: "It's ok to promote your own content, or content that you're otherwise vested in, but it should not constitute a majority of your contributio".

What gets removed in r/javascript

  • Low karma or a new account

    r/javascript 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/javascript posting questions

Can I post links in r/javascript?

Yes. r/javascript 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/javascript require karma to post?

r/javascript 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/javascript?

Yes, within reason. r/javascript allows self-promotion, but Reddit's sitewide 9-to-1 guideline still applies: accounts that mostly post their own links get filtered as spam regardless of sub rules. The sub's own wording: "It's ok to promote your own content, or content that you're otherwise vested in, but it should not constitute a majority of your contributio".

Is r/javascript strict?

Relaxed, by our estimate (10/100 on our strictness scale, from its measured removal rate, 7 rules, and its stated gates). About 6% 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/javascript?

Based on our sample of recent and top posts, activity and scores peak around Wednesday 4pm UTC and Saturday 2am 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/javascript?

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 6% of r/javascript posts disappeared within about a day of going up. Many removals are silent, so checking your draft first beats finding out after.
