# Reddit marketing: 19 of 27 subreddits limit self-promotion
> What the rules of 27 subreddits say about promoting software, where an AI agent helps, and which steps stay with a person. Our numbers, dated 11 October 2026.
The first thing our Reddit channel produced was a table. On 11 October 2026 it holds 27 subreddits, and next to each one the rules as someone read them in September. 19 of the 27 have written down a condition for what we came to do, which is mention a product. No post has gone out yet, so this article is about the preparation, because that's where the numbers are.
## What is Reddit marketing?
Reddit marketing for a software product is being useful in the threads where your buyer already asks a question, and naming the product only where it's the answer. It looks like support, not advertising: the reader arrived with a problem, and the reply either solves it or doesn't. [Reddit's own rules](https://redditinc.com/policies/reddit-rules) frame it from the platform's side: rule 2 asks you to participate authentically in communities where you have a personal interest, and not to spam. The page names no posting ratio and never says self-promotion, so the numbers live in each community's own rules. We don't have a comment that out-earned a month of ads, so this article doesn't open on one.
## What works on Reddit for a software product?
Five practices come up in the rules of our 27 subreddits again and again, and each has a community that wrote it down.
- **Answer the question asked.** r/startups wants posts that discuss methods, experiences and markets without the name or URL of your own project, so the answer carries the substance and the product waits.
- **Show the work.** r/ClaudeAI welcomes a project built with or for Claude when the post says what it does and how Claude helped, and when people can try it for free.
- **Disclose the product.** r/mcp allows self-promotion if you say how you are connected to the product, and bans the same promotion posted as a bystander.
- **Use the promo thread.** r/webscraping allows self-promotion only in its pinned monthly thread; r/AI_Agents sends projects to a weekly project display thread.
- **Never post the same text twice.** r/hermesagent removes a near-identical post that appears in 3 or more subreddits within 24 hours, and identical copy-paste every time.
The strictest number we found is in [r/SaaS](https://www.reddit.com/r/SaaS/): a maximum of 1 mention or 3 links every 60 days, affiliation disclosed at the beginning or end of the post or comment, and secondary accounts promoting the same product count toward the same limit. A violation leads to a ban and URL blacklisting. We read that in the community's sidebar on 11 October 2026.
## Where does an AI agent help?
An AI agent helps with the four jobs that eat the hours before a reply exists: finding threads, reading them whole, drafting in the voice of the account, and keeping a log of what was said where. The reader's side is [agents that read Reddit for you](/blog/ai-agent-browser): you tell the agent which subreddits and which question, and it comes back with a short list.
| Job | What comes back |
| --- | --- |
| Find | threads from the 27 subreddits where the product could be the answer, one line each |
| Read | the whole thread as a 5-line summary |
| Draft | a reply in the account's voice, with the facts it rests on |
| Log | what was said where and on which date, so nothing goes out twice |
A search round can be recorded once and replayed. Scalebrowser's workflows are [3 tools](/docs/agents/workflows) that record a stretch of agent work and replay it later, finding each element again on the page as it is and drawing a fresh rhythm for each profile.
### Which steps stay with a person?
Three steps stay with a person: posting, answering follow-ups, and judging tone. The account a reply goes out under belongs to somebody who reads what comes back, and a follow-up question a day later needs the same voice as the first answer. Tone is the third, and our map shows why: r/SaaS, r/Entrepreneur and r/LocalLLaMA ban AI-written text in their rules. In those three, the agent hands over the thread, the facts and the log, and the person writes the reply.
## What did our own Reddit channel show?
On 11 October 2026 our Reddit channel had 27 subreddits mapped, 19 of them with a written condition on promotion, and no post published. We read the rules of each community on 9 and 13 September, so they are 28 to 32 days old. That's too old to trust: the live sidebar of r/SaaS lists 11 rules on 11 October, and our September read holds 5, so every rule gets read again before a post goes out.
| What we counted | Result |
| --- | --- |
| Subreddits mapped | 27 |
| Founder communities | 6 |
| Communities where the audience discusses the problem | 10 |
| Niche communities | 6 |
| Competitor and platform communities | 5 |
| Own subreddit | 0 |
| Rules that name a condition for promoting your own product | 19 of 27 |
| of those, rules that limit it or confine it to a thread | 15 |
| of those, rules that welcome it under conditions | 4 |
| Subreddits with a promo thread | 6 of 27 (4 weekly, 2 monthly) |
| Subreddits that ban AI-written text | 3 of 27 |
| Subreddits with an entry barrier for a new account | 5 of 27 |
| Median members, 24 of 27 show a count | 127,376 |
| Subreddits with fewer than 100 members | 4 |
| Posting times sampled | 0 of 27 |
| Posts, comments, sign-ups | 0, 0, 0 |
Two of those rows shape the plan. Only 6 of 27 have a promo thread, so in the other 21 the only way in is an ordinary thread, and the rule that counts is the one about disclosure. And 4 of the 27 have between 9 and 36 members, which makes them listening posts at best.
The number you'd ask for first, sign-ups per comment, stays empty: with 0 comments posted, there's nothing to divide. The posting times are empty too, 0 of 27: the first sample reads each subreddit's 100 best posts of the last month, and that step hasn't run yet. When posts exist, this article gets a second table with posts, comments and sign-ups per comment, each with its date.
### Can a short video carry a Reddit post?
A short video can carry a post in the communities that allow one, and a run of the agent produces it as a by-product. r/SideProject switched image posts off and allows videos and links, according to our notes of 13 September, and r/ClaudeAI pins a thread called "Show us what you've created with Claude!" under the flair Built with Claude. Scalebrowser records a run and renders it into a demo video of the run; the [videos documentation](/docs/agents/videos) describes the recording.
#### Which listings come after Reddit?
Directories come after Reddit, because a listing is submitted once and then stays on one page with one link. The work there is a form, and the numbers are acceptances and visits; ours are in [directory listings with our numbers](/blog/directory-submission).
#### Where does the browser run?
The browser runs on the machine of whoever uses it, so every account stays signed in where its owner works. That's [the browser behind the drafts](/blog/ai-agent-browser): the agent reads and writes notes there, and a person posts. The [overview of use cases](/use-cases) lists the other jobs, and [repeat work](/use-cases/repeat-work) is the one this article is.
