Subreddits That Allow Self-Promotion: How to Check Any Community Yourself

Why every list of promotion-friendly subreddits goes stale

None of the Reddit policy pages we read lists the communities where promotion is welcome. The Reddit Rules say each community's culture is shaped by the rules its moderators enforce, and Rule 2 asks you to follow those rules, take part authentically where you have a personal interest, and not spam. Section 8 of the User Agreement lets moderators create and enforce their own rules, as long as they do not conflict with Reddit's terms, the Reddit Rules or the Moderator Code of Conduct.

So the answer for each community lives inside it, and changes whenever its moderators edit a rule. LeadsRover, which classifies subreddit rules pages, gives an example: r/ClaudeAI read as explicitly allowing promotion until a rules rewrite in summer 2026 left the topic unaddressed.

Lists also disagree at the same moment. In rules collected between May 30 and August 9, 2026, LeadsRover classed r/smallbusiness as no rule stated. OneUp Today's checker page, last checked July 13, 2026, reported that the same community limits business promotion posts to a weekly promote-your-business thread, with an exception for relevant replies. Same community, same summer, two different answers. A list cannot tell you which one still holds, so check the community yourself.

Where a community's rules live

The last row matters most for new accounts. The AutoModerator help page says moderators can set it to remove or flair posts by domain or keyword, hold content for review, flag potential spammers, and react to karma or a person's history. A community can welcome promotion on paper and still filter your link. If your posts vanish without a message, see our guide to hidden comments on new accounts.

The five postures a community can take

LeadsRover sorts communities into banned, restricted, allowed and no rule stated. Splitting restricted in two makes the next step clearer.

Allowed is rare. In LeadsRover's mid-2026 snapshot, among subreddits whose written rules take any position on promotion, 68.0% banned it, 29.1% restricted it and 2.9% allowed it. It is one third-party snapshot, but the lesson holds: your target is usually a thread or a condition.

A six-step check for any community

No shortlist yet? Start by finding the subreddits where your buyers ask: a community that allows promotion but has none of your buyers is no use to you.

1. Search the rules page
   Look for promot, advertis, self, link, spam, survey, flair and weekly. Copy the rule number and wording into your notes.
2. Read the description, sidebar and wiki
   Follow links to posting guides or recurring threads. Conditions often sit here rather than in the numbered rules.
3. Check the pinned posts
   Note whether a promotion thread exists, how often it runs, and its format, such as one comment per product.
4. Scroll a month of new posts
   See whether maker posts stay up, which flair they use, and which rules moderators quote when they remove something.
5. Check your own account
   A new account with little history may meet automated filters. Our guide to Reddit karma requirements explains why no single number applies.
6. Record and ask
   Write down the posture, the condition, where you read it and the date. If two places disagree or the rules are silent, message the moderators before posting.

Ask the moderators: a ModMail template

Reddit's Spam help page says moderators decide what counts as unwanted or spammy content in their communities, and that you can contact them for clarification. The Moderator Code of Conduct expects moderator teams to monitor and address ModMail regularly, so a short, specific question there is a normal request.

• Ask one specific question. Name the rule, describe the post, offer two options.
• Say who you are. Your role and product go in the first lines.
• Offer nothing in return. Section 8 of the User Agreement bars moderators from taking moderation actions in return for any form of compensation, gift or favor from third parties.
• Keep the answer. If another moderator removes the approved post later, you can show it politely.
• Accept a no. It still tells you how to take part: answer without links, or use the thread they name.

Dated examples from third-party checks

We have not checked these ourselves. They show what a useful note looks like (community, source, date, posture) and how quickly it ages. Check each rules page before acting on any line.

Rules that apply even where promotion is allowed

A permissive community cannot switch off Reddit's sitewide rules. Our guide to Reddit's self-promotion rules covers them in full; these are the ones people trip over.

• Frequency. The Spam help page says that if most of your contributions are links to a business you run or benefit from, be careful how often you post, or look at Reddit's advertising options. See Reddit Ads as an alternative.
• Repetition. The same page lists mass-posting repetitive content for exposure or financial gain, and bots that keep promoting products across communities, as spam. The same launch text in ten allowed communities in one day fits that description.
• Authenticity. Rule 5 says you need not use your real name, but must not intentionally mislead people or impersonate someone deceptively. A founder posing as a happy customer breaks it, whatever the community allows.
• Disclosure. The operator decides the wording, but Rule 5 bars intentionally misleading others, and the law can require material connections to be disclosed. In the US, 16 CFR 255.5 says that when an endorser has a connection to the seller that could change how much weight people give the endorsement, and the audience would not expect it, the connection must be disclosed clearly and conspicuously. A business relationship or a payment can be such a connection. Our disclosure templates give wording.

Permission to promote is permission to post something useful that happens to be yours. Lead with a lesson, an answer or real numbers from your own work, and put the product second. Our notes on writing a Reddit comment that is not spam apply to posts too.

Where Agent Agency fits

Agent Agency's Reddit agent keeps to daily limits and quiet hours and reads each community's rules, and in Approve mode every post, comment and DM waits for your OK. That does not replace the check above: no tool can promise how moderators will rule, and you answer for what is posted under your name. How it works describes the modes and limits.

Questions

Is the 90/10 rule a Reddit rule?

None of the current Reddit policy pages we read sets a posting ratio. Some communities write a ratio into their own rules, and LeadsRover lists ratio requirements among the conditions it found. If a community states one, follow that community's number.

Can I post the same launch in every subreddit that allows promotion?

That is risky even where each community allows it. Reddit's Spam help page lists mass-posting repetitive content for exposure or financial gain as an example of spam. Write each post for the community it goes to, space them out, and check each community's format rules.

How often should I recheck a community's rules?

Before each promotional post, and whenever a post of yours is removed. Moderators rewrite rules, and third-party trackers only notice a change when they next read the page. A dated note of what you read last time makes each recheck quick.
