How to Self-Promote on Reddit and Hacker News Without Getting Banned

Most advice about promoting on Reddit or Hacker News boils down to "don't be spammy." That's true, but it's not very useful. The harder question is where the line actually sits between genuine participation and self-promotion, and whether it's possible to do both at the same time.

It is, but it requires being upfront about what you're doing.

Why stealth promotion gets you banned

There's a whole category of tools and guides that treat social platforms like ad networks — find relevant threads, drop a comment that casually mentions your product, rinse and repeat. The logic is that if the mention feels natural enough, nobody will notice.

People notice. Reddit and Hacker News communities are full of users who spend hours a day reading threads. They recognise when an account only appears to recommend a specific product. They check post histories. On Hacker News, people will literally call you out in a reply if your comment history is nothing but plugs for the same tool.

The stealth approach fails for a practical reason too: it scales badly. The more "natural" mentions you post, the more obvious the pattern becomes. One or two might fly under the radar, but by the tenth, your account history tells a very clear story.

Why disclosure works better than you'd expect

This is the part that feels counterintuitive. Saying "I built this" or "full disclosure, I work on the team behind this" should, in theory, make people more sceptical of your recommendation. In practice, it does the opposite.

On Hacker News, founders openly sharing their work is not just accepted — it's the norm. "Show HN" exists specifically for this. Threads where a founder shows up, explains their reasoning, and engages with feedback tend to get more upvotes than anonymous product mentions. The community values directness.

Reddit is a bit different. Self-promotion rules vary by subreddit, and some communities are stricter than others. But even on Reddit, an honest "I'm the founder of X, here's how it might help" tends to get a better response than a comment that tries to look organic but clearly isn't. The Reddit self-promotion guidelines actually spell this out — the rule of thumb is that no more than 10% of your activity should be self-promotional, and when it is, you should be transparent about it.

The reason is trust. When you disclose your connection to a product, you're letting the reader make an informed decision about your recommendation. When you hide it, you're trying to manipulate that decision. People can sense the difference, even if they can't always articulate it.

How to self-promote without breaking the rules

It's not complicated, but it does require more thought than copy-pasting a template reply across multiple threads.

Lead with the answer, not the product

If someone asks "what's the best way to handle invoice reminders?", your reply should actually answer that question. Talk about the approaches that exist, mention alternatives that might work for their situation, and then — if your product is relevant — mention it alongside the others.

The test is simple: would your reply still be useful if you removed the product mention entirely? If yes, you're doing it right. If the whole comment falls apart without the plug, it's an ad dressed up as advice.

Be specific about your connection

"Full disclosure, I built this" is good. "I'm on the team that makes X" is fine. Even "I'm biased here because I work on X, but..." works. What doesn't work is vague phrasing designed to technically not lie while still being misleading — things like "I've heard good things about X" when you're the one who made X.

The phrasing matters less than the intent. If a reasonable person reading your comment would feel misled after learning your connection to the product, you haven't disclosed enough.

Match the platform's tone

Each platform has its own culture around self-promotion, and what works on one can backfire on another.

Reddit expects subtlety. Most subreddits have explicit self-promotion rules, and moderators enforce them. Your product mention should be a small part of a genuinely helpful reply. Reading the sidebar rules of any subreddit before posting is non-negotiable — some ban self-promotion entirely, others have specific threads for it, and others are fine with it as long as you're transparent.

Hacker News is more founder-friendly. Sharing something you built is normal, and the community generally respects people who show up and engage honestly with feedback. But HN has its own expectations — you're expected to engage with criticism directly, and comments that read like marketing copy get flagged quickly. The tone should be more like talking to a technical colleague than writing ad copy.

Other platforms like X (Twitter) or industry forums have their own norms, but the underlying principle is the same: understand what the community considers acceptable before you start posting, and when in doubt, over-disclose rather than under-disclose.

Don't reply to everything

Not every thread that mentions a problem your product solves is worth jumping into. If the conversation is about a general topic and your product is only tangentially related, forcing a mention in there does more harm than good. It makes your account look like it exists solely to promote, which undermines the genuine contributions you've made elsewhere.

Being selective also means your recommendations carry more weight. If someone checks your post history and sees hundreds of comments all pushing the same product, every one of those comments loses credibility. If they see mostly genuine participation with the occasional relevant product mention, those mentions actually land.

How your post history affects credibility

This is the part most people skip. Even if every individual comment you post is honest and helpful, the overall pattern of your account activity tells its own story.

An account where 80% of the comments mention the same product doesn't look like a genuine community member, regardless of how well-written each comment is. Platforms like Reddit track this kind of pattern, and so do the communities themselves.

The fix is straightforward but requires discipline: participate in conversations where you have genuine expertise but no product to promote. Answer questions, share experiences, engage in discussions that have nothing to do with what you're selling. This isn't just about gaming the ratio — it's about actually being a member of the communities you're posting in.

A good benchmark is the 90/10 split: roughly 90% of your activity should be genuine participation with no self-promotion at all, and the remaining 10% is where you mention your product when it's truly relevant. This isn't a rigid rule, but if your ratio is anywhere near 50/50, something needs to change.

How to respond when someone calls you a shill

It happens. Someone will accuse you of shilling, even if you've been transparent. The response matters more than the accusation.

Don't get defensive. Don't delete the comment. Acknowledge their concern, point to your disclosure, and move on. Something like "Fair point — I did mention I'm the founder in my comment, but I understand the scepticism. Happy to answer questions about alternatives too." This kind of response usually defuses the situation and sometimes even earns respect from the community.

What you absolutely shouldn't do is argue about it, create alt accounts to defend yourself, or brigade the thread with supportive comments. All of these are worse than the original accusation and can result in permanent bans.

The long game

Ethical self-promotion is slower than the spray-and-pray approach. You won't see results in the first week. But the results compound in a way that stealth promotion never does.

A genuine reputation on Reddit or Hacker News is an asset that grows over time. People start to recognise your username. They trust your recommendations because they've seen you give helpful, unbiased advice before. When you do mention your product, it carries weight because you've earned the right to be heard.

The alternative — burning through accounts, dodging spam filters, and hoping nobody checks your post history — is a treadmill that gets harder the longer you're on it.

Pick the approach that still works a year from now.
