Reddit Rules Explained: The Three Layers That Get Brands Banned (+ Infographic)

Most people who go looking for “the rules of Reddit” expect one page. There isn’t one. There are three separate layers, they are enforced by three different parties, and the one that removes the most brand posts is the one that was never written down.

Here is how the system actually works, and where marketing teams keep tripping.

The Three Layers, In Order of How Often They Bite You

Layer	Written by	Enforced by	Penalty
Content Policy	Reddit	Admins, sitewide	Account suspension, site ban
Subreddit rules	Each mod team	Mods, per community	Post removal, subreddit ban
The unwritten culture	Nobody	Users, via downvotes	Buried post, hostile comments

Marketers tend to read the first one, skim the second and ignore the third. The frequency of enforcement runs in exactly the opposite order.

Layer 1: Reddit’s Content Policy (Sitewide)

This is the sitewide floor. It applies in every community, and breaking it risks your account, not just your post. The Content Policy covers things like harassment and threats, sharing personal information, impersonation, illegal transactions, and vote manipulation.

For a normal brand account, most of it is not a live risk. Two parts are:

Vote manipulation. Asking colleagues to upvote a post, using multiple accounts, buying upvotes, or coordinating votes in a Slack channel. Reddit detects this better than people assume, because it correlates accounts by behaviour and not just by IP address. This is the fastest way for a company to lose an account permanently.

Spam and inauthentic behaviour. Posting the same link across many communities, operating a network of accounts that all promote the same thing, or running an account that exists solely to post your own domain.

Neither of these comes with the kind of warning you might get for a subreddit rule break. Enforcement is account-level.

Where to read it: Reddit publishes the Content Policy at redditinc.com/policies/content-policy. Read the current version rather than a summary, because it is updated periodically.

Layer 2: Subreddit Rules (Per Community)

Every subreddit sets its own rules. They cannot override the Content Policy, but they add plenty on top of it. Two communities covering the same topic can have opposite policies on whether you may link your own site.

Subreddit rules appear in the sidebar on desktop and under the About tab in the app. Larger communities usually keep a fuller version in the wiki, which is where the specifics live: minimum account age, minimum karma, whether self-promotion is allowed at all, which post flairs are mandatory, whether links are permitted or only text posts.

The part marketers miss: many subreddits enforce rules through AutoModerator, which removes a post within seconds based on account age, karma, domain or keywords. The removal is often silent. Your post looks normal when you view it while logged in, and does not exist for anyone else. If a post gets zero views in an hour, check it in a logged-out browser window before concluding that Reddit hates you.

The 9:1 rule. You will see this cited as a Reddit rule: nine ordinary contributions for every one self-promotional post. It comes from Reddit’s old self-promotion guidance and is no longer a sitewide rule, but plenty of subreddits still enforce something like it in their own rules, and the underlying logic is exactly how mods judge an account. A profile whose entire history is links to one domain reads as spam regardless of what any ratio says.

Layer 3: The Unwritten Rules (Reddiquette and What Replaced It)

Reddit used to publish a document called reddiquette, an informal etiquette guide for behaving like a community member. It is still online, but it has been archived rather than maintained, and parts of it describe a version of Reddit that no longer exists.

The etiquette it described did not go anywhere. It just stopped being written down. This is the layer that decides whether a post gets engagement or gets buried, and it is enforced by ordinary users through downvotes, which no appeal process can reverse.

The norms that matter most to a brand:

• Disclose your affiliation. If you work for the company being discussed, say so in the comment. Reddit forgives a disclosed interest and never forgives a discovered one.
• Read the room before posting. Every community has a tone. A post written in press-release voice signals immediately that its author does not participate here.
• Do not repost your link across communities. Dropping the same URL into ten subreddits in one afternoon reads as spam to both mods and users.
• Answer comments. A brand that posts and disappears is treated as an advertiser. A brand that replies for two days is treated as a participant.
• Do not argue with downvotes. Complaining about being downvoted reliably produces more downvotes.
• Search before you post. If a question was asked last week, the community will say so.
• Use the right post format. Flair, tags, title conventions, and the sub’s preference for link posts versus text posts.
• Do not delete a post that went badly. It looks like hiding, and screenshots already exist.

Twelve pairs, one per row: what earns a brand goodwill on the left, what gets the post removed or buried on the right. Save it or send it to whoever runs your accounts.

The Rules Nobody Warns Marketers About

A few specifics that come up constantly in client work:

New accounts cannot do much. Many communities block posts from accounts under a certain age or karma threshold. If the plan is to register an account and post on Monday, it will not work. Accounts need history before they need a campaign.

Your domain may already be blocked. Subreddits and Reddit itself maintain domain blocklists. If a previous agency or an over-enthusiastic employee spammed your URL years ago, your domain can be silently filtered in communities you have never visited. Test with a throwaway post before building a strategy on a domain you have not verified.

Mod decisions are final in their community. There is no appeal to Reddit for a subreddit ban. Admins do not overturn mod decisions about who may post in a community they run. A polite modmail is the only route, and rudeness in modmail ends the conversation permanently.

Reddit Ads follow separate rules. Everything above governs organic posting. Paid campaigns are governed by Reddit’s advertising policies, a different document with its own restrictions on claims, targeting and creative. A campaign can be perfectly compliant as an ad and still break the rules if you post the same content organically. If paid is where you are headed, our Reddit ads agency page covers that side.

How to Check the Rules Before You Post

A short routine that prevents most removals:

1. Open the subreddit and read every rule in the sidebar, including the ones that look boring.
2. Open the wiki if there is one. The real restrictions usually live there.
3. Sort by Top of the month and read five posts. That tells you the format and tone that work better than any rule text.
4. Search the subreddit for your brand name and your competitors. You will learn whether the community already has an opinion.
5. Check the modmail policy. Some communities require permission before anything promotional, and asking first turns a ban into a green light.
6. Post, then stay for the comments.

The Honest Summary

Reddit’s written rules are not hard. Almost nobody gets removed for failing to understand the Content Policy. Brands get removed because they arrive as advertisers in a place where everyone else arrived as a person, and no rule you can read covers that.

The three layers are worth learning in order. But if you only fix one thing, fix the third.

Doing this consistently, across multiple communities, with an account history that mods trust, is what our Reddit community management service exists to do. If you would rather not learn these rules by getting banned, talk to us.
