Does this work for private or banned subreddits?

For private subreddits, we return a 🔴 verdict citing the private flag — we cannot read their rules. For banned or deleted subreddits, you'll see a "not accessible" error.

How fresh is the data?

Results are cached for 7 days per subreddit. Mod rule changes are rare enough that a weekly cache strikes the right balance between cost and freshness.

Why is the verdict for r/X wrong?

Our parser uses ~30 regex patterns against rule text — it can miss nuanced wording. The verdict always cites the rule that drove it, so you can see what we matched (or didn't). Email us with the example and we'll add a pattern.

Do you use Reddit OAuth?

No. RedNudge intentionally uses only Reddit's public, unauthenticated endpoints. That means there are a few signals (e.g., distinguishing a shadowbanned account from a non-existent one) we can't resolve — but we never need a Reddit login.

What's the difference between this and Reddit's own "rules" page?

Reddit just shows you wall-of-text rules. We extract the outreach-relevant signals — self-promo policy, karma gates, age gates, link/flair requirements — and give you a single verdict so you can make a posting decision in seconds.

Can I check multiple subreddits at once?

Not yet — single subreddit only. A bulk / CSV variant is on the roadmap if this tool ranks. Use the Subreddit Finder tool to discover candidate subs first, then run them through this checker one at a time.

Does the verdict guarantee I won't get banned?

No — mods can ban for any reason, and Reddit-wide rules apply on top of subreddit rules. The verdict is a strong heuristic, not a permission slip. Read the cited rules before posting.

How is this different from RedShip or Reddinbox?

Most subreddit tools focus on stats (subscribers, post timing). This one focuses on the specific question marketers ask before posting: can I promote here? We translate the rules into a single yes/no verdict with the receipts.

Subreddit Rules Checker — see if r/X allows self-promotion

Before you post, find out whether a subreddit allows self-promotion, link posts, or outreach — without reading through pages of rules. Paste a subreddit name and we read its rules + posting settings and give you a single verdict: 🟢 outreach-friendly, 🟡 conditional, or 🔴 do not post. Every verdict cites the exact rule that drove it.

How the verdict is built

We fetch the subreddit's rules and posting settings from Reddit's public API. Our parser looks at structured signals (private/quarantined/restricted, link posts disabled, mod-approved-only) plus rule-text signals (no self-promotion, 9:1 / 10% rule, karma minimums, account-age minimums, mod-approval requirements, mandatory post flair). Any red signal makes the subreddit 🔴; any yellow signal makes it 🟡; otherwise it's 🟢.

Why we cite the rule

Every verdict shows the rule index and snippet that triggered it, so if our parser misreads a nuance you can see it immediately and judge for yourself. No black-box scoring — just transparent attribution.

When to use this

Use it before posting a launch announcement, before pitching your product, or before building an outreach list. If the verdict is 🔴, we'll suggest friendlier subreddits with our Subreddit Finder. If it's 🟡 or 🟢, we surface the topic you came for and pre-fill it on RedNudge to start monitoring leads in that subreddit.
