Reddit's sitewide policy does not ban self-promotion outright. It asks you to post where you have a genuine interest and to keep self-promotional content to a small share of your activity, the old "10% rule" from reddiquette. The real risk is in each subreddit's own rules, which is where founders get banned. I audited 999 subreddits and got banned twice myself while building this tool, so this is what the rules say plus what happens when you miss one.
Reddit's sitewide rules, read today
Reddit's Content Policy is short on specifics about self-promotion. Rule 2 asks members to "post authentic content into communities where you have a personal interest, and do not cheat or engage in content manipulation (including spamming, vote manipulation, ban evasion, or subscriber fraud) or otherwise interfere with or disrupt Reddit communities." That is the whole legal basis for almost every self-promotion rule you will run into. Your presence has to be genuine, not just a delivery vehicle for a link.
Reddit's help center defines spam as "repeated or unsolicited actions, whether automated or manual, that negatively affect redditors, communities, and/or Reddit." The examples it gives are things like mass-posting repetitive content for exposure or financial gain, and repeatedly posting the same or similar links across threads. One disclosed reply to a relevant post doesn't cross that line. Twenty near-identical comments dropping the same URL into twenty threads does.
The number most founders have heard, the 10% rule, comes from reddiquette rather than the Content Policy itself. Reddiquette has long put it this way: if more than about 10% of your activity is submitting your own stuff, you're probably a spammer in Reddit's eyes. You can be a redditor with a website, but not a website with a Reddit account. That line has not changed in years, though Reddit's own documentation increasingly talks in terms of behavior patterns rather than a strict percentage. Moderators do not run the math on your post history. They look at whether your last ten comments are all the same pitch.
None of this is enforced sitewide automatically. Individual moderator teams each write their own promotion rule on top of the sitewide policy, and that's the layer that gets founders banned. I read the Content Policy page, the Reddiquette page, and Reddit's Spam help page on 2026-09-14 to write this section. Reddit updates these pages without much notice, so if you're reading this months later, check the current wording before you rely on it.

What we found auditing 999 subreddits
Sitewide policy tells you the floor. Subreddit rules tell you what happens to your account. I audited 999 subreddits since 2026-09-05, reading each one's posted rules where they exist (742 of them had posted rules; the rest I judged from the sidebar description) and classifying the promotion policy as banned, restricted, or allowed.
Excluding the 189 subreddits where there was not enough evidence to call it either way, the split across the 810 I could verify was:
- Banned: 49 percent
- Restricted: 31 percent
- Allowed: 20 percent
Roughly half ban outright or confine it to a designated thread. Just under a third let you promote under specific conditions: a thread, a ratio, a flair, or mod approval. One in five allows it more or less freely, and these tend to be smaller communities built for this purpose.
Here are 23 examples from the audit, with the rule each verdict was based on.
| Subreddit | Verdict | Rule cited |
|---|---|---|
| r/startups | Banned | Rule 2 prohibits direct sales, advertisements, or promotional posts of any kind; promotion confined to designated threads. |
| r/smallbusiness | Banned | Rule 3 prohibits business promotion posts outside the weekly thread; rule 1 restricts posts to questions. |
| r/marketing | Banned | Rules 2 and 7 prohibit self-promotion and shilling. |
| r/webdev | Banned | Rule 3 prohibits self-promotion; rule 4 bans commercial promotions. |
| r/sales | Banned | Rule 2, No Selling or Self Promotion, immediate permanent ban. |
| r/technology | Banned | Do not submit anything you have personally written or any projects, websites, or companies you are affiliated with. |
| r/personalfinance | Banned | Rule 2 prohibits self-promotional advertising of products owned by the poster. |
| r/shopify | Banned | Rule 5 prohibits soliciting and self-promotion; rule 10 bans dev research and app validation posts. |
| r/saas | Restricted | Promotion allowed only if relevant and helpful; feedback requests confined to the weekly thread. |
| r/entrepreneur | Restricted | Rule 2 prohibits self-promotion as the primary purpose but allows citing your own content within a helpful answer. |
| r/datascience | Restricted | Rule 7 limits self-promotion to a 1:9 ratio. |
| r/macapps | Restricted | Rule 2 limits self-promotion to once per month and requires disclosing the relationship in comments. |
| r/indiehackers | Restricted | Self-promotion allowed once with the SHOW IH flair, for feedback. |
| r/nocode | Restricted | Disclosure, a company flair, a value-add post, or the monthly launch thread. |
| r/chatgpt | Restricted | Rule 3 confines self-advertising to the weekly self-promotional mega thread. |
| r/photography | Restricted | Rule 4, self-promotion only in weekly community threads, limited to 10 percent of submissions. |
| r/podcasting | Restricted | Product promotion only in the weekly Services thread or with mod approval; rule 9 requires affiliation disclosure. |
| r/sideproject | Allowed | Sidebar describes a place for sharing side projects and receiving feedback. 833k members. |
| r/buildinpublic | Allowed | Rule 3 permits sharing work with context and asking for feedback. |
| r/genealogy | Allowed | Rule 3, posting your own site or work is OK in moderation. |
| r/indiebiz | Allowed | Launch and feedback venue. |
| r/roastmystartup | Allowed | Launch and feedback venue. |
| r/craftingworld | Allowed | Rule 6, selling work through the community is totally fine as long as you don't spam the feed. |
Looking at 999 subreddits, two patterns emerge. First, "banned" almost never means banned from posting. It means promotion is confined to a designated thread, which shows up in 32 of the banned verdicts in my audit. You can still take part. You just can't do it in a regular post or reply. Second, restricted subreddits are all over the map in what they ask for, which is the next section.
What "restricted" actually means
The 252 restricted verdicts in my audit break into four buckets, based on what the rules asked for:
- A designated thread or day: 50 subreddits. Promotion is fine, but only in the weekly self-promo thread, the monthly launch thread, or a specific day.
- A participation ratio, the 10% rule: 35 subreddits. Your self-promotional posts have to stay under some fraction of your total activity in that community, commonly 1 in 10 or 1 in 9.
- Flair: 27 subreddits. You need a specific post flair (Show IH, Resources, company flair) before you can mention your own product.
- Mod approval: 27 subreddits. You message the moderators first and get a yes before you post or reply with a link.
These conditions stack. r/nocode, for example, asks for disclosure and a company flair and offers a monthly launch thread as an alternative. r/podcasting wants the weekly Services thread or mod approval, plus disclosure. Treating "restricted" as one category is how founders get caught, since the actual condition is usually buried past the first few rules most people read.
Two bans, two rules I hadn't read
I run Radar on my own other products, ColorHer and SHIP FM, and before that I was just a founder replying to threads by hand. I got a 28-day ban from r/SaaS first. Then, on 4 September 2026, I got a permanent ban from r/startups.
Both replies answered the question and were specific to the post. Neither read like an ad. But both broke a rule further down the subreddit's list that I hadn't read before posting. Most bans follow this pattern: good answers that violate a condition, a thread requirement, a ratio, or a flair the poster never checked for. It's rarely spam in any obvious sense.
I started building Radar's repository the next day, 5 September 2026. The first rules audit in the database is dated the same week. The two bans are the reason the product reads every subreddit's actual rules before it tells you whether to reply, and why it labels each community promote, soft promote, or hang out rather than just green-lighting a pitch.
A checklist before you reply
If you are doing this by hand, a few minutes here saves you a ban.
- Read the subreddit's full rules, not just the sidebar summary. The condition that gets you banned is usually rule 3 or later, not rule 1.
- Check for a designated thread. Search the subreddit for "self-promotion," "showcase," or "feedback" pinned posts before you reply in a normal thread.
- Look for a ratio. If the rules mention a percentage or a ratio like 1:9, count your last ten posts in that community.
- Check for a required flair. Some subreddits will remove an otherwise fine post just for missing a flair tag.
- Disclose. "Full disclosure, I built this" costs you nothing and is what most restricted subreddits require before they let a link through.
- Once per subreddit, then wait. Post a mention, then leave that subreddit alone for a while before you mention the product there again. Most bans come from repetition, not from a single reply.
- In banned communities, help without promoting. Answer the question, skip the product entirely. You can still be useful without pitching.
Where Radar fits
Radar reads each subreddit's actual rules before it scores a thread and labels the community as promote, soft promote, or hang out. It only puts a product mention in a draft where rules allow it, disclosed, once, in the final third. If you post something else entirely, that's on you. But Radar won't hand you a draft that breaks the rule it just read. Scan my site free to see how it handles your product before you reply to anything.

FAQ
Is self-promotion actually against Reddit's rules?
Not sitewide. Reddit's Content Policy asks you to post authentic content in communities where you have a real interest and not to spam or manipulate content, but it does not ban mentioning your own product. The specific limits, thresholds, and outright bans come from each subreddit's own rules, which is why the same kind of reply can be fine in one community and a ban in the next.
What is the 10% rule on Reddit?
It's a reddiquette guideline, not an official Content Policy rule, that says roughly 10% or less of your posting and comment activity in a community should be self-promotional, with the rest genuine participation. Some subreddits write a version of this into their own rules directly, often as a 1:9 ratio, and a handful enforce it more strictly than others.
Can you promote your product on Reddit at all?
Yes, in the subreddits where the rules allow it, which my audit put at about 20% of subreddits with clear rules, plus another 31% that allow it under a specific condition like a designated thread, a flair, or mod approval. Roughly half ban it outright or confine it to a thread most people never find.
What happens if I break a subreddit's self-promotion rule?
It ranges from a removed post to a temporary ban to a permanent one, and moderators set that themselves per subreddit. I got a 28-day ban from r/SaaS and later a permanent ban from r/startups, both for replies that were helpful but broke a rule I hadn't read before posting.
How do I find a subreddit's actual self-promotion rule?
Open the subreddit, click the full rules page rather than relying on the sidebar summary, and read past the first couple of rules, since the promotion condition is usually further down. Search the subreddit itself for terms like "self-promotion," "showcase," or "feedback" to check for a pinned or recurring thread built for exactly this.
