Big audiences attract spam, and moderators of big subreddits answer with blanket bans and automoderator filters. Small communities get less spam and are often glad when a founder shows up to help. That makes the long tail of small subreddits the friendliest place to mention a product, and the big ones the place where only genuinely helpful answers survive.
Written rules
74% of subreddits have a rule about promotion, ads or spam
Subreddits whose rules mention promotion, advertising or spam
A rule that mentions promotion is not always a ban: some allow it on a weekly thread or with disclosure. That is why Bazzly classifies strictness separately.
Where buyers are
73% of buying posts are in strict subreddits

Strict does not mean silent. Buyers in r/SaaS, r/smallbusiness and r/careerguidance ask for help every week; what gets removed is the comment that reads like an ad. More on what those buyers write in our study of 16,331 buying-intent posts.

Playbook
How to comment in a strict subreddit
- 1Answer the question first
The first two sentences should be useful to someone who will never click a link. Moderators remove comments that exist to sell, not comments that help.
- 2Name options, not just yours
A short comparison that includes your product as one option reads as advice. A comment about only your product reads as an ad.
- 3Skip the link where links are banned
In strict subreddits, the product name is often enough: interested readers search for it. A bare link is the fastest way to get removed.
- 4Use an account with history
Many strict subreddits filter new or low-karma accounts automatically, whatever the comment says. Bazzly posts from aged accounts for this reason.
The case against
Four reasons to discount these numbers
Every dataset has blind spots. These are the ones that matter most here, so you can decide how much weight to give each number.
- 1This is Bazzly data, not a random sample of Reddit
Bazzly only scans the subreddits and searches its customers care about, and its customers are mostly software, AI, marketing and career products. Subreddits and industries outside that mix are thin or missing, so read the numbers as "what Bazzly customers run into", not as a census of Reddit.
- 2Strictness is a classification, not a rulebook
Each subreddit is classified by an AI model reading its description and rules. Since August 2026 the model is calibrated against the comment-removal rates Bazzly observes, but subreddits classified before that keep their label until their rules change. Moderators also enforce rules unevenly, so a "lenient" label is a starting point, not permission.
- 3Rule mentions are a keyword match
The 74% figure counts subreddits whose rule text mentions self-promotion, promotion, advertising or spam. A rule can mention promotion to allow it on certain days, so this overstates outright bans and is reported separately from strictness.
- 4Member counts change
Subscriber counts were read when Bazzly last refreshed each subreddit; size buckets use those values.
How we measured this
Methodology
- Sample
- 1,907 active, non-NSFW subreddits in Bazzly's database (1,905 classified)
- Window
- Classified up to October 11, 2026
- Source
- Bazzly's subreddit database (every subreddit Bazzly has looked up for a customer), read-only queries, as of October 11, 2026. Buying-intent shares use the customer data and exclusions of the buying-intent study.
- Subreddit set
- Every subreddit Bazzly has looked up for a customer (watched, suggested or posted in), excluding NSFW, banned, private and not-found communities: 1,907 active subreddits, of which 1,905 could be classified.
- Strict
- Rules explicitly ban self-promotion, tool recommendations or marketing content, or moderators actively remove it. Rules that ban promotion while allowing it elsewhere still count as strict, because that is how they are enforced.
- Moderate
- Self-promotion is allowed with conditions: disclose your affiliation, contribute first, post only on certain days or threads, or limit how often.
- Lenient
- No rule against product mentions; the community welcomes tool recommendations, comparisons and people sharing what they built.
- Classifier
- Bazzly's classification of each subreddit's self-promotion rules (strict, moderate, lenient), made by an AI model reading the subreddit's description and rules. Since August 2026 the model is calibrated against the comment-removal rates Bazzly observes; subreddits classified earlier keep their label until their rules change.
- Buying-intent posts
- Posts scored 0.75 or higher for at least one Bazzly customer brand, September 15 to October 11, 2026 (same definition as the buying-intent study). Listed subreddits were matched by at least 3 brands.
Customer data is aggregated and no customer can be identified from it; customers are named only in case studies they agreed to. Medians are used instead of averages wherever a few large values would distort the picture.
FAQ
Which subreddits allow self-promotion?
About 20% of the subreddits Bazzly has classified are lenient, mostly small ones: the median lenient subreddit has 11,093 members. Lenient communities where buyers still ask for help include r/SideProject, r/buildinpublic, r/microsaas and r/CRMSoftware. Check any subreddit with Bazzly's free subreddit rules checker before posting.
Can you promote your product on Reddit?
In most large subreddits, not directly: 80% of subreddits with more than a million members are strict about self-promotion. What works is answering the question in the thread and mentioning a product only where it genuinely helps, in subreddits whose rules allow it.
Why are big subreddits stricter?
Bigger audiences attract more spam, so moderators of large subreddits ban self-promotion outright and rely on automoderator rules. Small communities have less spam to fight and often welcome a founder who shows up to help.
What happens if you break a subreddit's self-promotion rule?
Usually the post or comment is removed, and repeat offenders get banned from the subreddit. Accounts that are banned from many subreddits or reported for spam can be suspended by Reddit sitewide.
