Subreddit Rules Decoded: What 'No Self-Promotion' Really Means

"No self-promotion" is the most common rule in subreddits founders care about — and the most misread. It describes a spectrum, not a wall.

The four actual variants

Absolute ban. No product mentions, period — even helpful ones in comments. Found in subs burned by spam (r/smallbusiness enforces hard). Respect it: value-only comments, no mentions. These subs still pay off through presence and karma — you're building the account that converts elsewhere.

Contextual. Promotion allowed when genuinely relevant and disclosed — the most common real-world reading. "Someone asking for exactly what you built" is the paradigm case. The product answers the question; the disclosure handles the trust.

Quarantined. Promotion allowed only in designated weekly/monthly promo threads. Fine — mark the thread day, participate normally otherwise.

Karma-gated. Promotion permitted only above karma/account thresholds. The rule literally encodes "earn the right".

The unwritten modifier

Every rule is enforced by a human mod exercising judgment. The same comment gets removed in the hands of a strict mod and upvoted under a lenient one. The variables mods actually weigh: your account history, whether the comment reads as answer or ad, and whether you look like you'll be back for non-commercial reasons.

The practical test

Before posting commercially in any sub, ask: if a mod reads my last ten comments, do they see a member or a campaign? The rules are the floor; the history is the verdict. Our rules analyzer fetches the written half — the unwritten half you build yourself.
