How to Grow on Reddit Without Getting Banned

Bans on Reddit feel arbitrary from the outside. They are not. The detection logic is consistent, mostly behavioural, and almost entirely undocumented. What follows is a diagnostic guide structured the way a founder usually encounters the problem: as a sequence of questions that surface only after something has already gone wrong.

What actually triggers a Reddit shadowban?

Almost never the words. Reddit's site-wide spam systems and most subreddit AutoModerator configurations weight behaviour heavily and content lightly. The signals that consistently precede shadowbans, inferred from thousands of post-mortems, are these:

A two-day-old account posting at adult-account volume. A comment-to-post ratio that skews post-heavy when real users skew comment-heavy by ten to twenty times. Reply latencies measured in single-digit seconds, repeated across multiple threads. The same outbound domain in a majority of comments, regardless of whether the comments themselves are useful. Concentration of activity in a single subreddit cluster that maps cleanly to one product category. Voting patterns where seasoned users downvote the account's content quickly and consistently.

Notice that none of these are about what the account says. You can write the most thoughtful comment of your career, and if it ships from an account that looks behaviourally like a marketing tool, it gets filtered before any human reads it.

Why do mods auto-remove half my posts?

Because most subreddits worth marketing in have AutoModerator rules that gate by karma, account age, or both, and your account does not clear the threshold. The thresholds are not published. Common floors are 10, 50, 100, 500, and 1 000 combined karma; common age floors range from 7 to 90 days.

When AutoModerator removes a post for failing a karma check, you typically receive no notification. Logged in, your post still exists. Logged out, it does not. The removal looks identical to a successful submission from your side of the screen. This is by design. Spammers who know they have been filtered iterate; spammers who do not know move on.

The fix is mechanical. Read the subreddit's wiki and stickied rules before posting. If the rules do not state a floor, search the subreddit for "karma requirement" and read the past three threads where someone asked. If you still cannot tell, post a comment first. Comments are gated less aggressively than posts and will tell you whether the account is visible at all.

Is karma a real defence?

Partially. Karma alone does not protect an account; behaviour does. But low karma stacks penalties that compound the effect of every other risk signal.

A 10-karma account writing a borderline comment gets filtered. A 2 000-karma account writing the same comment passes. The comment is identical; the account context is what shifts the verdict. Karma functions as an aggregate signal of "this account has shown up enough times to be worth treating like a person." Above roughly 500 comment karma, most general subreddits stop applying the harshest filters. Above 1 000, the account has the benefit of the doubt almost everywhere.

The corollary is that karma earned in karma-farming subreddits or on a single viral submission does not buy the same protection. AutoModerator configs increasingly check for karma diversity across subreddits, not just totals. An account with 5 000 karma all from r/AskReddit jokes will be treated more cautiously than one with 800 karma spread across twenty communities.

What does Reddit actually see when I use a Chrome extension versus an API bot?

These are not the same shape of traffic, and the difference matters more than founders realise.

API-based bots authenticate with a bearer token, hit Reddit's servers from a known datacentre IP, and produce request patterns that look nothing like a browser session. No JavaScript execution, no asset loads, no scroll events, no idle time. Reddit's anti-spam team has been pattern-matching this shape for over a decade and is excellent at it.

Headless-browser tools, the ones that run Chromium on a server somewhere, are a step better but still detectable. Headless Chrome leaks signals that real Chrome does not: missing browser plugins, predictable fingerprint hashes, datacentre IPs, automation flags that some libraries fail to scrub.

A real Chrome session running on a real laptop on a real residential IP produces traffic Reddit cannot meaningfully distinguish from manual use, because it is manual use, accelerated. The detection vector that catches API and headless bots simply does not apply. The remaining risk is behavioural pacing, which is on the operator, not the tooling.

This does not make session-based automation invincible. If you set it to ship 200 comments an hour, you will still be banned. The behaviour is inhuman regardless of how human the request shape looks. The tooling removes one failure mode. It does not remove the need to behave like a person.

Why does my multi-account setup keep getting flagged together?

Reddit links accounts through several lateral signals: browser fingerprint, IP and IP range, account creation timestamps clustered within minutes of each other, near-identical posting cadence patterns, and cross-account vote behaviour that looks like a ring. When one account in a cluster gets flagged, the cluster gets flagged.

We have seen founders lose four or five accounts in an afternoon because they were all signed in from the same browser profile on the same machine. The accounts were operating cleanly on their own metrics; the cluster was the problem.

The operationally honest answer is that scaled multi-account outreach on Reddit is harder than it looks and rarely worth the maintenance. One account, deeply established, will produce more pipeline over twelve months than five accounts run carefully and rotated when one fails. If multiple founders at the same company want presence, give each a real account they personally operate, on their own machine, on their own connection. Do not pool accounts in tooling.

What's the safest way to mention my product?

The safest mention is the one made under direct question. "Has anyone built X" or "what do people use for Y" is an explicit invitation. Disclosing your relationship to the tool ("disclosure: I work on this") and answering the question substantively, with at least one alternative also mentioned, lands almost universally. The disclosure costs nothing and removes the suspicion that powers most reports.

The next safest mention is in a comment thread you have already been participating in for weeks, where the OP's problem fits your tool exactly, and where you frame it as one option rather than the answer. "We solved this with [tool] but if you want a lighter approach, [alternative] works fine for that scale" reads as a real recommendation from a real operator.

Unsafe mentions: linking in a thread you have not engaged with, dropping a URL with a tracking parameter, mentioning the product in three subreddits within an hour, using a discount code, or anything that reads like a press release. Each of these has been pattern-matched by mods for years and will draw a removal at minimum, a ban at worst.

What's the right pacing to actually grow without flags?

Pacing matters more than total volume. Five to fifteen well-placed comments per day, spread across several hours, in subreddits where the account has visible history, is the safe band. Twenty to forty comments per day, mostly in target subreddits, with the occasional link, is the medium band. Above fifty per day, concentrated in product-relevant subreddits, with promotional tone, is the high band that consistently precedes bans.

The other variable is ramp. The most common ban pattern we see is not steady high volume; it is a step function. An account warms up properly for ten days at five comments per day, hits 300 karma, then jumps to 50 outreach comments per day on day eleven. The jump itself is the signal. Doubling weekly is fine. Doubling daily is not.

What do I do once I've already been flagged?

Diagnose first. Log out, search for your recent comments in the subreddits where you posted them. If they appear logged in but not logged out, you are filtered. The filter may be subreddit-level or site-wide.

For subreddit-level removals, message the moderators directly. Be brief, acknowledge the rule you violated, do not argue. Many subreddit-level shadowbans are reversible if caught in the first week and the request is polite. After three or four weeks of continued posting while filtered, the appeal usually fails because the activity pattern reads as spam ignoring the signal.

For site-wide shadowbans, submit at reddit.com/appeal. Site-wide reversals are less common but happen, especially when the underlying activity was within reasonable behavioural bounds and the flag was a false positive. Provide context. Acknowledge anything you would do differently. Do not relitigate the decision.

If neither works, the account is done. Starting over with a new account on the same machine, same IP, same patterns produces a re-ban inside days. Starting over genuinely, with a different browser profile, different cadence, and a longer warmup, sometimes works. More often the cleaner path is to invest the next six months in a single real account operated patiently, rather than burning a second one trying to recover the first.

The accounts that survive on Reddit long-term are not the ones with the cleverest tooling. They are the ones that look, from the outside, indistinguishable from a person who happens to be unusually generous with their time.
