This is the mechanics guide, not a channel strategy list. Account setup, karma basics, how to actually read a subreddit before you post, AutoMod's real conditions, and the difference between posting and commenting, laid out step by step.
Quick answer: Lurk first, build karma through comments, read the subreddit's own rules and wiki before posting, keep self promotion at or under the 10% or less rule of thumb, and expect AutoMod to check your account_age and comment_karma before a human ever sees your post.

Most Reddit marketing advice skips straight to strategy, which subreddit to pick, what story angle converts, when to launch, without covering the mechanical layer underneath all of it. That skip is why so much advice fails in practice. A perfect post idea posted from a two day old account with no karma gets caught by AutoMod before a single human reads it. Understanding account age thresholds, the wiki's actual self promotion guidance, and how AutoMod and the mod queue interact is not a prerequisite you can shortcut. It is the thing that decides whether any strategy on top of it ever gets seen at all.
Do these roughly in order. Skipping straight to step 8 without steps 1 through 7 is how most beginners end up removed, held by AutoMod, or shadowbanned in their first week.
Create a real account. Pick a username you would be comfortable attaching to your niche, verify your email, and skip the auto generated default handle. Mods and AutoMod both treat obviously random usernames as a spam signal.
Lurk before you post anything. Spend your first several days just reading. Notice what gets upvoted, what gets removed, and how regulars talk to each other in the subreddits you care about.
Build karma through comments, not posts. Answer questions you can genuinely help with. Comment karma accumulates faster than post karma and it is what most AutoMod rules actually check.
Read the subreddit's sidebar and full rules page before you post. Every subreddit sets its own self promotion policy, posting days, and required formatting, and the community rules always override general Reddit norms.
Check the subreddit's wiki for a self promotion or spam policy. Many communities publish an explicit page (often at r/subreddit/wiki/rules or a linked wiki page) spelling out exactly what they allow.
Confirm you clear AutoMod's account age and karma thresholds. Subreddits commonly configure AutoMod to auto remove or hold posts from accounts below a set account_age or comment_karma value, so check the rules for any stated minimums first.
Apply the wiki's 10% or less rule of thumb to your own links. Reddit's official self promotion guidance is a ratio you self police, not a hard platform limit, but subreddits and mods do notice when it is ignored.
Choose a post or a comment based on what you are actually trying to do. A new thread asks the whole subreddit for attention, a comment adds value to a conversation that is already happening.
Format the title and body the way that subreddit expects. Match flair requirements, avoid title case shouting, and use Markdown headers or bullet points only if the community's other top posts do too.
Post when your target subreddit is actually active, then stay and reply. Timing gets you the first wave of eyes, replying to every comment in the first hour is what keeps the post alive after that.
Every subreddit is its own small country with its own laws. Checking these five things takes ten minutes and prevents most removals before they happen. Tools like MediaFast's subreddit finder can shortcut some of this research, but you should still read the rules yourself before posting.
A subreddit with 400K subscribers but no new post in three days is not actually 400K people looking at your content. Sort by new and check how often threads actually get replies.
Old Reddit's sidebar (or new Reddit's About panel) lists numbered rules. Read every one, not just the ones about self promotion, since off topic or format rules get posts removed just as often.
Many subreddits link a wiki page from the sidebar with specifics: allowed days, required flair, or a flat ban on links. Reddit's own selfpromotion wiki is the platform-wide baseline every subreddit can tighten.
Check recent removed posts (visible to you if you sort by new and compare against comment counts) for patterns. If every link post from a low karma account vanishes, AutoMod is filtering by account_age or karma.
Message the mod team a genuine question before you post anything promotional. A same day reply means an active mod team who will notice you later. Radio silence for a week means you are on your own.
Rules lists look intimidating because they are numbered and dense, but almost every subreddit's rules fall into the same handful of categories. Knowing the category tells you how strictly it will be enforced.
| Rule type | What it usually means |
|---|---|
| Self promotion / spam rule | Sets a ratio, a flat ban, or a specific approval process for links to anything you own or are paid to promote. |
| Off topic / relevance rule | Removes content that does not directly relate to the subreddit's stated purpose, regardless of promotional intent. |
| Format / title rule | Requires a specific title structure, a flair tag, or a text body instead of a bare link, often enforced by AutoMod automatically. |
| Low effort / repost rule | Removes content that mirrors a recent post or adds nothing new, common in larger, higher traffic subreddits. |
| Verification / flair approval rule | Requires manual mod approval or a specific verified flair before certain post types, common in professional or expert focused subreddits. |
Before a moderator ever sees your post, AutoModerator has usually already decided whether to let it stay. Per Reddit's AutoModerator documentation, these are the conditions subreddits configure most often against new posters.
| Condition | What it checks | Why mods use it |
|---|---|---|
| account_age | Compares to the age of the poster's account, for example account_age: < 60 hours. | Blocks brand new or throwaway accounts from posting the moment they are created. |
| comment_karma | Compares to the author's total comment karma. | Filters accounts that have never engaged in conversation before trying to post or link something. |
| link_karma | Compares to the author's total post or link karma. | Catches accounts built entirely on posting links elsewhere with no comment history at all. |
| title / body keyword match | Flags or removes posts whose title or body text matches specific words or phrases mods configure. | Auto removes obvious spam phrasing, banned competitor names, or link shorteners without a human reviewing first. |
"My post disappeared" can mean three completely different things mechanically, and each one needs a different response.
Only that one post or comment is gone. Your account and other content are unaffected. Almost always AutoMod or a rule violation specific to that item.
Everything you post or comment is hidden from other users platform wide, while it still looks normal to you. This is account level, not subreddit specific.
You are blocked from posting or commenting in one specific community, but your account works normally everywhere else on Reddit.
If a post or comment does not trip an automatic removal, it is not necessarily free and clear. Reports from other users, and posts AutoMod is configured to hold rather than remove, land in the subreddit's mod queue for a human to review. A moderator can approve it, remove it with a stated reason, or leave it pending if the team is inactive.
This is why two nearly identical posts in the same subreddit can have different outcomes. One got manually approved by a mod who happened to check the queue, the other sat unreviewed until it aged out of relevance. Messaging the mod team after posting, especially in smaller subreddits, is a legitimate way to get a held post looked at faster.
A genuinely helpful, non promotional post gets removed within seconds of publishing. The poster assumes a mod judged the content and reacts by arguing in modmail. In most cases the real cause is mechanical: the account was two days old and tripped an account_age condition the subreddit had configured, and no human ever looked at the post at all. Checking the account age and karma requirements before posting would have caught this before it happened, which is exactly what step 6 of the playbook above is for.
These are not the same action wearing two hats. They carry different risk, different karma requirements, and different jobs to do.
| Aspect | Posting a new thread | Leaving a comment |
|---|---|---|
| Karma usually needed first | Often none required by Reddit itself, but many subreddits set an account_age or karma floor in AutoMod before a new post is even allowed to stay up. | Almost none. Most subreddits let brand new accounts comment immediately, which is why comments are the fastest way to start participating. |
| Visibility if it flops | A dead thread sits at the bottom of new with zero upvotes, visible to almost nobody after the first hour. | A comment with zero upvotes still sits inside a live thread that other people are reading, so it still gets some incidental exposure. |
| Removal and ban risk | Higher. New threads are what AutoMod and self promotion rules are built to catch, especially from accounts without history. | Lower, provided the comment answers the actual question instead of just dropping a link. |
| Best use case | Launch announcements, AMAs, story style posts, or genuinely new questions the subreddit has not covered. | Ongoing presence, answering questions, and mentioning your product only when it is the honest answer to what someone asked. |
| Time to write well | 30 minutes to several hours for a story style post with real structure. | 2 to 10 minutes per comment, which is what makes daily comment marketing sustainable. |
| How the wiki's 10% rule applies | Counts heavily against your ratio if it links to your own content. | Counts too if it links out, but most helpful comments do not link anywhere and cost you nothing against the ratio. |
Ask around and you will hear Reddit has a strict "90/10 rule" for self promotion. It does not, at least not as an official policy. What actually exists is guidance published on Reddit's own self promotion wiki, and the language there is softer and more specific than the community shorthand suggests.
"A general rule of thumb is that 10% or less of your posting and conversation should link to your own content."
Notice what that sentence does not say. It does not say zero. It does not say a hard platform enforced cap. It is a rule of thumb covering your whole account's activity, posts and comments combined, not a per post quota. Individual subreddits are free to set a stricter rule in their own sidebar, and many niche communities do exactly that, so always check the local rules on top of this baseline.
The wiki's ratio is the platform wide default, but individual subreddits layer their own version on top. These five patterns cover most of what you will run into.
Any link to your own product is removed on sight, no ratio applies. Common in large general interest subreddits.
Self promotion is allowed as long as it stays at or under roughly 10% of your total activity in that subreddit and across Reddit generally.
Self promotion is confined to a specific pinned thread or a designated day of the week, posted anywhere else it gets removed.
You must message the mod team and get explicit sign off before your post goes up, sometimes tied to a required flair.
Self promotion is allowed if you clearly disclose your affiliation with the product, undisclosed promotion is treated as the actual violation.
The right time to post is whenever your specific subreddit's regulars are online, which you learn by watching a few days of new posts and noting when replies start piling up. One documented exception is AMAs: guidance built specifically for that format has pointed to around 12 p.m. ET as a strong start time, held open for at least 2.5 hours, with Thursdays tending to drive the most traffic and a second wave of attention roughly 2 hours after the initial post. That is AMA specific advice, not a rule for every post type.
Open the top posts of the month in your target subreddit and copy their structure, not their words. Some communities want a plain, short title and a wall of text. Others want Markdown headers, bullet points, and a tl;dr at the bottom. Flair is often mandatory and posts without it get auto removed regardless of content quality.
Reddit posts and comments render Markdown, not a visual editor. These are the syntax patterns that actually show up in well formatted posts across most subreddits.
| You type | It renders as |
|---|---|
| **text** | Bold text |
| *text* | Italic text |
| # Heading | A large section heading |
| - item | A bulleted list item |
| [label](url) | A clickable hyperlink with custom label text |
| > text | A block quote, useful for citing a rule you are replying to |

"How to Use Reddit - Complete Beginner's Guide" by Howfinity.
Posting before lurking. Showing up on day one with a promotional thread is the single fastest way to get removed or shadowbanned. Spend real time reading first.
Confusing 10% or less for never mention it. The wiki's guidance is a ratio, not a ban. Founders who over correct into total silence about their own product waste the channel entirely.
Copy pasting the same post everywhere. Identical text across subreddits reads as spam to both AutoMod and human readers who browse more than one community.
Skipping the sidebar and wiki. Every subreddit sets its own posting days, flair rules, and self promotion policy. Assuming Reddit wide norms apply everywhere gets posts pulled.
Treating a removed post as a personal attack. Most removals are AutoMod matching a keyword or karma threshold, not a mod judging your product. Read the removal reason before reacting.
Disappearing after posting. A post with no replies from its author reads as a drop and run. The comments section, not the post itself, is where trust actually gets built.
Ignoring flair before publishing. Plenty of subreddits auto remove any post missing a required flair tag. Set flair at the point of posting, not after a removal notice arrives.
Assuming one throwaway account fixes karma problems. A second account with zero history trips the exact same account_age and comment_karma conditions the first one did. There is no shortcut around building real history.
Karma is a running total of upvotes minus downvotes, tracked separately for posts (link karma) and comments (comment karma). A few mechanical details matter more than most beginners realize.
Reddit does not display raw vote counts in real time. What you see is fuzzed to make vote manipulation harder to script, so two people looking at the same comment minutes apart can see slightly different numbers.
Comment karma has a floor. Per Reddit's own AutoModerator documentation, comment karma will not go below negative 100, so a single pile of downvotes cannot push your account into an ever worsening spiral.
Karma is not a currency and cannot be spent, gifted, or redeemed for anything on the platform. Its only real function is as an input to AutoMod's account_age and comment_karma conditions and as a rough trust signal to human readers. A reddit karma calculator can help you estimate how long it takes to clear a given threshold.
Step 1 of the playbook above sounds trivial, but the choices you make while signing up follow your account for as long as you use it.
Skip the digits Reddit auto suggests. A username with a random number string reads as disposable to both AutoMod's pattern matching and to human readers scanning a comment thread.
Verify your email immediately. Some subreddits' AutoMod configurations specifically check for a verified email before allowing a post to stay up, on top of the age and karma checks.
Add a profile picture and a short bio. An account with zero customization sitting alongside a promotional comment is one of the easiest tells for both mods and other users.
A running count of net upvotes minus downvotes on your posts and comments. It signals account history more than it signals influence.
A topic specific community with its own rules, moderators, and culture, denoted with an r/ prefix.
The rules and description panel for a subreddit, visible on desktop or under the About tab, where most posting rules are published.
Reddit's rule based bot that mods configure to auto remove, hold, or flag posts and comments matching set conditions like account age or karma.
Any post or comment that links to something you own or are paid to promote. Governed platform wide by the 10% or less rule of thumb.
An account level restriction where a user's posts and comments are hidden from everyone except themselves, usually without direct notice.
Sharing the same submission into a different subreddit using Reddit's native crosspost feature, distinct from manually retyping the same text.
A tag attached to a post or a user, often required by subreddit rules to categorize content before it is allowed to stay up.
The holding area where posts and comments AutoMod flags, or that other users report, wait for a human moderator to approve or remove.
Reddit's messaging system for contacting a subreddit's moderator team directly, the right channel for asking about an ambiguous rule.
A secondary account used to post anonymously or start over. It does not bypass AutoMod's account age or karma conditions, since those reset to zero.
Submitting content, including your own, that has already been posted before. Many subreddits remove reposts automatically within a set time window.
Reading a sidebar, guessing at your karma ratio, and watching for AutoMod patterns is manageable for one subreddit. It gets tedious across ten. MediaFast scores ban risk and matches your draft's tone to a subreddit before you hit submit, which is useful once you already understand the mechanics above and just want fewer of them to hold in your head at once.
MediaFast checks account age, karma, and subreddit rules before you post, so you catch what AutoMod would catch, before it catches you.
The mechanics questions beginners ask most.
There is no platform wide minimum, but many subreddits configure AutoMod to hold or remove posts from accounts below a set comment_karma or account_age threshold. A few hundred comment karma and a couple of weeks of real activity clears most of these filters.
It is community folklore, not an official Reddit policy. The actual guidance, from Reddit's own self promotion wiki, is that a general rule of thumb is that 10% or less of your posting and conversation should link to your own content. People shorthand that as 90/10, but the wiki never uses that ratio.
Moderators configure AutoMod with conditions like account_age, comment_karma, or matching keywords in the title or body. If your account or post trips a configured condition, AutoMod removes or holds it automatically, before any human moderator sees it.
Comment first. Comments carry lower ban risk, need less or no karma, and let you learn a subreddit's tone before you risk a thread that AutoMod or a mod might remove on sight.
Read the sidebar or About panel, then look for a linked wiki page covering self promotion or spam specifically. If nothing is posted, message the mod team directly and ask before you post.
It depends entirely on the subreddit's own active hours, which you can gauge by watching when new posts actually pick up replies over a few days. For a scheduled event like an AMA, marketing guidance built for that specific format has pointed to around midday and a Thursday slot as reliably higher traffic windows, but a regular post should follow the audience you are actually trying to reach.
Check the removal reason first if Reddit shows one, since most removals are AutoMod matching a specific condition like account age, karma, or a keyword, not a judgment call by a mod. If no reason is given, message the mod team through modmail and ask directly rather than reposting the same content.
Reddit's rules govern the content and behavior of a post, not the tool used to write it. The same self promotion ratio, subreddit rules, and AutoMod conditions apply whether you typed the draft yourself or used a tool like MediaFast to help structure it.
