How Reddit decides what founders can post

Reddit gates visibility through three layers: karma thresholds, account age requirements, and per-subreddit AutoModerator rules. A founder’s first posts usually fail at least one of the three, which is why they tend to disappear quietly instead of being rejected with an error. None of it is personal: the gates exist because thousands of promotional accounts arrived before you did, and the machinery treats every newcomer the same way until the record says otherwise.

It is worth taking the three layers one at a time, because each fails differently and each asks something different of you.

Layer 1: karma thresholds

Reddit karma is the score an account accumulates as other users vote on its posts and comments, and across the site it serves as a rough proxy for trust. Communities lean on it because it is hard to counterfeit at quality. A number built from thousands of small judgments by real participants says more about an account than anything the account could say about itself.

Most subreddits of any size set a karma floor below which you cannot post, comment, or both. The floors vary widely. Some communities count karma earned anywhere on Reddit, while stricter ones count only what you have earned inside that specific subreddit, which a newcomer has none of by definition. Almost no community publishes its number, deliberately, since a published threshold becomes a target.

The consequence for a founder is blunt. The subreddits with the most commercial gravity, the large rooms where your customers actually ask questions, attract the most spam, so they run the highest floors. A fresh account can post in quiet corners of the site almost immediately. The places it most wants to be heard are exactly the places that will not let it speak yet.

Layer 2: account age

Karma can be earned quickly by someone willing to put in concentrated effort. Time cannot. That is why communities weight account age: it is the one credential no amount of effort accelerates. Spam operations burn through accounts and replace them with new ones, so an account that has existed for months and behaved ordinarily the whole time is, statistically, far less likely to be disposable.

Age compounds with karma rather than substituting for it. Most gating rules require a minimum of both, so a three-day-old account with respectable karma fails just as surely as a two-year-old account that has never commented. The pair is cheap to satisfy together and expensive to satisfy separately, which is the design. The combination selects for accounts that have spent real time participating.

There is no clever response to this layer, and that is fine. The waiting period is usable. Commenting, answering questions, and being ordinarily present builds karma while the calendar does its work, so both clocks run at once. Founders who treat the first weeks as dead time arrive at week six with an aged account that still cannot clear a karma floor.

Layer 3: AutoModerator

The first two layers are mostly enforced by the third. AutoModerator is the rule bot included with every subreddit, configured independently by each moderator team, and it is where age and karma floors usually live in practice. Its rules test each new submission against whatever conditions the moderators wrote: account age, karma, the domain of any link, banned words in a title or body, minimum text length, whether the account has a verified email.

Two properties of AutoModerator shape how failure feels. First, it is stateless. It evaluates every submission in isolation, against your account’s properties at the instant you press post. It does not track how often you post or remember what you submitted yesterday; if something is throttling your posting frequency, that pressure comes from Reddit’s sitewide systems, not from a subreddit’s bot. Second, silence is its default. Many configurations remove content without telling the author, so the post looks perfectly normal from your own session while no one else will ever encounter it. A founder can post into the same community for weeks without realizing nothing has been visible.

And because every community writes its own rules, the same post can go up untouched in one subreddit and be removed on arrival in the next. There is no single rulebook to learn. There are thousands of them, and most are unpublished.

What failing looks like

The signature of failing a gate is absence, not rejection. The post goes up, you can see it, and then nothing: no votes, no replies, no notice. New founders usually read this as indifference. More often it means nobody was shown the post at all.

The two kinds of silence are worth telling apart, because they call for different responses. An AutoModerator removal is local. One community’s configuration declined your post, your account remains in normal standing everywhere else, and the remedy is to keep participating until you clear that community’s floors. A shadowban is the sitewide version, applied to the account itself by Reddit’s spam systems rather than by any subreddit, and it hides everything you do across the entire site.

The diagnostic is the same for both. Look at your content from outside your own session, by opening the post or your profile in a private browser window where you are not signed in. A single post missing from a single subreddit points to a local rule. A profile that shows nothing anywhere points to the sitewide layer, which is a much more serious problem.

The 90-day implication

Taken together, the three layers enforce a sequence: participation before promotion. They are also the reason shortcuts fail, though not quite in the way people expect. The automated gate counts an account’s karma across all of Reddit, so karma accumulated anywhere does clear the number. What it does not do is survive the read that follows. A purchased aged account carries a history that does not match its new behavior, and a profile of low-effort activity in unrelated communities reads as exactly what it is to the first moderator or regular who opens it. Clearing the threshold buys you a look, not a welcome. And activity engineered to clear it quickly is the burst pattern the sitewide spam systems are tuned to catch.

The gates cannot be gamed, but they can simply be met. Ninety days of ordinary, useful presence clears the age floors, builds karma where it counts, and leaves a record that reads as a person rather than a campaign. The deeper point is that the work the gates demand and the work credibility demands are the same work. By the time the machinery lets you speak, the community has reasons to listen. What to do with that standing, the ratios, the timing, the mistakes that burn accounts, is the subject of the full guide to Reddit marketing for founders.

Hermenea agents are built around exactly these constraints, earning standing through participation first and treating the gates as the operating environment rather than an obstacle. If that is the posture you want to run, you can join the waitlist.
