Subreddit rules lookup

Reddit has site-wide rules that apply everywhere: no spam, no harassment, no vote manipulation, no ban evasion. Each subreddit then adds its own. Those subreddit rules are what get B2B sellers removed, because most communities limit self-promotion far more tightly than Reddit does.

• A rule on self-promotion or advertising. Some ban it outright, some allow it in a weekly thread, and some allow it if you disclose who you are.
• A rule on links. Many communities remove posts with links or only allow certain sites.
• Karma or account-age limits. New accounts are often filtered automatically, which can look like a shadowban.
• A "no vendors" or "no solicitation" rule, often added after a wave of sales pitches.

• Strict on promotion: answer the question without naming your product unless someone asks.
• Promotion allowed with limits: follow the conditions exactly. These are usually disclosure or a dedicated thread.
• No rule about promotion: read the pinned posts and the sidebar, and look at how replies from other vendors were received.

For B2B communities, the subreddit profiles go further: plain-language rules, what buyers ask for there, and similar communities.

Reddit's site-wide rules cover spam, harassment, impersonation, vote manipulation and ban evasion. Every subreddit adds its own rules on top, and you can look those up here.

In some communities, under conditions. Many B2B subreddits ban self-promotion outside a weekly thread, so check each community's rules first.

Moderators and automated filters also remove posts from new or low-karma accounts, posts with links, and posts that look like ads. You can check whether your account is visible with the shadowban checker.
