You spent an hour writing the perfect Reddit post. You hit submit. You get a confirmation screen. But when you check the subreddit, your post is nowhere to be found.
No notification. No removal reason. Just silence.
That's AutoModerator at work — and it's one of the most frustrating experiences for anyone trying to get traction on Reddit.
Here's the thing: Reddit AutoModerator removes millions of posts every day, the vast majority without any human moderator ever seeing them. If you're a marketer, a brand, or even just a new user trying to participate in a community, understanding how AutoMod works is non-negotiable.
This guide breaks down exactly how AutoModerator works, which filters catch the most people, how to detect silent removals, and how to work with the system instead of constantly fighting it.
TL;DR: Reddit AutoModerator in 2026
- AutoModerator is a bot every subreddit can configure with custom rules using YAML syntax.
- Common filters: minimum karma thresholds, account age requirements, domain blacklists, keyword matching.
- Silent removals are real — your post appears live to you but is invisible to everyone else.
- Most subreddits require at least 1–5 years of account age and 50–500+ karma for unrestricted posting.
- You can check for silent removal using a shadowban checker or by viewing your post while logged out.
- Messaging moderators politely for manual approval works more often than most people realize.
- The best long-term strategy is building genuine Reddit standing — or starting with established Reddit accounts that already clear the filters.
What Is Reddit AutoModerator?
AutoModerator (often called "AutoMod") is a site-wide bot built into Reddit's platform. Every subreddit has access to it, and moderators configure it through a wiki page called r/subredditname/wiki/config/automoderator.
It runs automatically the moment any piece of content — a post, a comment, or even a user — matches a defined rule. The actions it can take include:
- Removing the post or comment (with or without notifying the author)
- Approving content automatically (useful for trusted users)
- Adding flair to posts or comments
- Leaving a comment explaining removal (though many subreddits skip this)
- Reporting content to human moderators for review
- Filtering content into a moderator queue for manual review
The key distinction that trips up most users: removal and filtering are not the same thing. When AutoMod removes a post, it's gone from the public feed immediately. When it filters a post, the post sits in the mod queue pending human review. In both cases, you may see the post as live on your own screen because Reddit shows you your own content regardless.
Over 15,000 subreddits actively use AutoModerator rules, and top communities often have dozens of rules running simultaneously. A single post can trigger multiple rules at once.
Common AutoMod Rules That Affect Marketers
If you're doing anything commercial on Reddit — promoting a product, driving traffic to your site, or building brand presence — these are the filters you'll hit most often.
Karma Thresholds
The most common AutoMod rule across all major subreddits. A typical configuration looks like this:
---
type: submission
author:
comment_karma:
minimum: 100
post_karma:
minimum: 50
action: remove
action_reason: "Account karma too low"
---
This rule removes any submission from an account with fewer than 100 comment karma or fewer than 50 post karma. The author never receives a formal notification in most cases — the post simply disappears.
Karma thresholds vary wildly by subreddit. A small hobby community might require 10 karma. A major finance or entrepreneurship subreddit might require 1,000+. There's no public directory of these thresholds, which means you often won't know what the requirement is until you get filtered.
Account Age Requirements
Account age filters are nearly as common as karma filters, and they're often stacked together:
---
type: submission
author:
account_age:
minimum: 30
unit: days
action: filter
action_reason: "Account too new"
---
This sends any post from an account under 30 days old into the mod queue. Some subreddits set this as high as 365 days — meaning a brand-new account literally cannot post there for an entire year, regardless of karma.
Why do subreddits use age filters? Because spam accounts are almost always brand new. A 3-year-old account with 400 karma is far less likely to be a throwaway spam bot than a 2-day-old account.
This is one of the main reasons marketers who need to post immediately find it necessary to start with established Reddit accounts rather than creating new ones.
Domain Blacklists
Subreddits frequently block specific domains from being submitted. This is one of the most targeted forms of AutoMod filtering:
---
type: link
url:
includes:
- "competitor-site.com"
- "known-spam-domain.net"
action: remove
---
Domain blacklists often include:
- Known spam or affiliate link domains
- Specific websites the community has had problems with
- Competitor platforms (e.g., YouTube links blocked in a Vimeo community)
- URL shorteners, which many subreddits ban entirely
Some subreddits go further and whitelist only approved domains, meaning any link not on the approved list gets removed automatically. This is common in news communities and professional subreddits.
Keyword and Phrase Filters
AutoMod can scan the full text of titles and post bodies for specific words or phrases:
---
type: submission
title+body:
includes-word:
- "discount code"
- "use my link"
- "affiliate"
- "buy now"
action: remove
action_reason: "Promotional language detected"
---
This catches overtly promotional language in post text. Marketers who write posts that sound like ad copy — even subtly — often trigger these rules. Phrases like "check out my," "I made this," "limited offer," and "sign up using" are common trigger phrases across subreddits.
Flair Requirements
Many subreddits require posts to have flair before they're visible:
---
type: submission
is_flair_required: true
action: remove
message: "Please add flair to your post before submitting."
---
This one is actually user-fixable — add the required flair before submitting. But if you don't know the requirement exists, you'll lose the post.
Silent Removals — How to Detect Them
Silent removal is arguably the most frustrating aspect of AutoMod for new users and marketers. Here's exactly what happens:
- You submit a post.
- Reddit shows you a success screen.
- You can see your post in the subreddit feed — but only when you're logged in.
- Everyone else sees nothing. The post doesn't exist in the public feed.
- You never receive a notification explaining what happened.
This is called a "shadow removal" and it's distinct from a full shadowban. A shadowban makes your entire account invisible. A shadow removal affects only that specific piece of content.
How to check if your post was silently removed:
Method 1: Log out and check. Open the subreddit in an incognito window while not logged in. If your post doesn't appear there but appears when you're logged in, it was removed.
Method 2: Check your profile while logged out. Navigate to your profile page in a private window. If the post shows on your profile but not in the subreddit, it was removed (your profile content stays visible to you regardless).
Method 3: Use a shadowban checker. A shadowban checker can help you determine whether your account itself has been flagged, which would explain systematic post removal across all subreddits.
Method 4: Direct URL test. Copy the direct URL to your post (e.g., reddit.com/r/subreddit/comments/abc123/). Open it in a private window. If you get a 404 or "page not found" error, it was removed. If you can see the post directly but it's not in the subreddit feed, it was filtered to the mod queue.
The key stat to know: according to Reddit's own transparency reports, AutoModerator handles a significant portion of all content removals across the platform, with major subreddits having removal rates north of 60% for new accounts.
Account Age and Karma Thresholds Across Popular Subreddits
Thresholds vary enormously. Here's a general breakdown of what you're likely to encounter based on subreddit category:
Low-barrier subreddits (karma farming / new user-friendly):
- r/FreeKarma4U, r/karma, r/NewToReddit — minimal or no restrictions
- r/AskReddit — very low threshold, mostly spam filters only
- r/memes, r/funny — low karma requirement
Mid-tier subreddits (common for most communities):
- Minimum 50–100 comment karma
- Account age: 7–30 days
- Examples: r/todayilearned, r/explainlikeimfive, r/technology
High-barrier subreddits (professional, financial, or large communities):
- Minimum 200–1,000 karma (combined or category-specific)
- Account age: 90–365 days
- Examples: r/investing, r/entrepreneur, r/startups, r/personalfinance
Invite-only or verified communities:
- Additional verification beyond AutoMod (mods manually approve new members)
- Examples: Various professional communities, SFW porn subs, verified trading groups
The Reddit karma guide covers how to build karma quickly if you're starting from zero. But if you need posting access immediately, bypassing this ramp-up period requires either strong existing accounts or a very patient approach.
Domain Blacklists and URL Filtering
Beyond individual domain blocks, AutoMod also supports pattern-based URL filtering. Moderators can block entire TLDs, URL patterns, or known shortener services:
---
type: link
url:
includes:
- "bit.ly"
- "tinyurl.com"
- "t.co"
- "amzn.to"
action: remove
action_reason: "URL shorteners not permitted"
---
Why do URL shorteners get blocked so heavily? Because they obscure the final destination. Reddit communities have been burned repeatedly by shortened links leading to malware, affiliate traps, or off-topic content. The ban on shorteners is almost universal among serious subreddits.
If you're sharing links as a marketer:
- Always use the full, unshortened URL
- Use clean URLs without excessive UTM parameters (UTMs trigger some keyword filters)
- Make sure your domain isn't on any known spam lists
You can check your domain's Reddit reputation by searching site:reddit.com "[yourdomain.com]" in Google. If the search returns threads full of complaints or spam reports, subreddit mods have likely already blacklisted you.
The Self-Promotion Ratio and How AutoMod Enforces It
Reddit's official self-promotion guidelines have long suggested a 10:1 ratio — for every 1 promotional post you make, you should have 10 genuine contributions. This isn't a hard rule, but it reflects the community expectation.
AutoMod can enforce a version of this through domain tracking:
---
type: link
url:
domain:
- "yourdomain.com"
author:
post_karma:
maximum: 100
action: remove
action_reason: "New accounts may not post their own domain"
---
This removes any link to a specific domain submitted by accounts with low karma — effectively preventing brand-new accounts from doing any domain-level promotion.
More sophisticated setups track submission history. Some subreddits analyze whether a submitting account's post history consists disproportionately of links to a single domain. If it does, the account gets flagged as a spammer even if each individual post looks legitimate.
The Reddit self-promotion guidelines are worth reading in full if you're building a presence on Reddit. The Reddit marketing guide covers how to build a compliant promotional strategy that works within these constraints.
You can also check your Reddit Contributor Quality Score — the Reddit CQS is a newer platform-wide signal that affects how your content is weighted in feeds, independent of AutoMod.
How to Message Mods for Manual Approval
When AutoMod removes or filters your post, you have a legitimate option that most people never use: message the moderators directly and ask for manual approval.
This works more often than you'd expect, especially if:
- Your content is genuinely relevant to the community
- You explain the situation honestly (not defensively)
- You've made some effort to participate in the subreddit before asking
How to reach out correctly:
-
Use the "Message the Moderators" button on the subreddit sidebar (desktop) or via the three-dot menu (mobile). Do not message individual mods directly.
-
Write a short, non-defensive message. Example:
Hi, I recently submitted a post titled "[your post title]" but I believe it may have been caught by AutoModerator due to my account being relatively new. The post is [brief description]. I've been a member of the community for [X time] and genuinely think this would be useful for readers here. Would you be willing to take a look and approve it if it meets the community standards?
-
Include the direct link to your post so mods can find it in the queue immediately.
-
Don't follow up more than once. Moderators are volunteers. Spamming modmail is the fastest way to get permanently banned.
-
Accept the outcome. If they say no, accept it gracefully. Arguing with mods never ends well.
The reality is that most moderators want quality content in their subreddits. A politely worded modmail message from a real person with a legitimate post gets approved a meaningful percentage of the time.
Strategies for Working With (Not Against) AutoMod
Understanding AutoMod changes your approach entirely. Here's what separates people who consistently get traction on Reddit from those who keep getting silently filtered.
Build karma before you need it. The biggest mistake marketers make is creating a Reddit account the same week they want to start promoting. Spend 30–60 days building genuine karma first through comments and non-promotional posts. See the Reddit karma guide for specific tactics.
Check subreddit rules before posting. Most subreddits with strict AutoMod rules document their requirements in the sidebar or in a pinned "rules" post. Read them. The karma and account age minimums are often listed explicitly.
Avoid promotional language in post text. Even in subreddits that allow self-promotion, post text that sounds like ad copy triggers keyword filters. Write like a community member sharing something useful, not like a marketing email.
Use your full domain URL. Skip the URL shorteners entirely. Always link to the canonical, full URL of your content.
Warm up accounts in low-restriction subreddits first. Contribute genuine comments in communities like r/AskReddit or hobby subreddits where you can participate authentically. This builds both karma and a credible post history.
Start with established accounts. If you need immediate access to high-barrier subreddits, established Reddit accounts with existing karma and account age are the only way to bypass the waiting game entirely. This is standard practice for professional Reddit marketers.
Track which subreddits remove your content. Keep a simple spreadsheet of where your posts go live vs. get filtered. After a few weeks you'll have a clear picture of which communities are accessible to your current account standing.
AutoMod Configuration for Subreddit Moderators
If you moderate a subreddit (or are building one), AutoModerator is your first line of defense against spam and low-quality content. Here's a practical starter configuration that covers the most common use cases.
Basic spam and new account filter:
---
type: submission
author:
comment_karma:
minimum: 10
account_age:
minimum: 7
unit: days
action: filter
action_reason: "New account — queued for review"
---
Domain spam filter (blocks known spam domains):
---
type: link
url:
domain:
includes:
- "spammydomain.com"
- "known-affiliate-farm.net"
action: remove
action_reason: "Domain not permitted in this community"
---
Promotional language filter:
---
type: submission
title:
includes-word:
- "promo code"
- "discount"
- "affiliate"
- "referral"
action: remove
---
Auto-approve trusted users:
---
type: submission
author:
is_contributor: true
action: approve
---
This approves posts from users you've manually added as approved contributors — useful for giving verified community members a bypass around karma requirements.
Full AutoMod documentation is available on Reddit's official wiki at reddit.com/wiki/automoderator. The Reddit Content Policy also outlines what AutoMod rules can and cannot do from a platform-wide enforcement perspective.
One important note: AutoMod rules are YAML-formatted and are highly sensitive to indentation and syntax. A single misplaced space can break an entire rule block. Test rule changes carefully before deploying to a live subreddit.
FAQ: Reddit AutoModerator
Why was my Reddit post removed with no explanation?
Almost certainly AutoModerator. The most common reasons are: account too new, karma below the subreddit's minimum threshold, your domain is blacklisted, or your post title contained a flagged keyword. To confirm, view your post in a private/incognito window while logged out. If it doesn't appear, it was removed or filtered.
Why was my Reddit post removed after being up for a while?
AutoMod runs at submission time, but human moderators can also remove posts manually at any time afterward. If your post was visible for hours and then disappeared, a moderator (human) likely removed it after reviewing the queue — or a user report triggered a secondary review. Check the subreddit rules to see if your post might have violated any of them.
Can I see why AutoMod removed my post?
Sometimes. If the subreddit's AutoMod is configured to send removal reason messages, you'll receive a notification in your Reddit inbox. Many subreddits skip this step to reduce modmail clutter. If you didn't get a message, assume it was a silent removal and use the manual methods above to diagnose why.
How do I bypass AutoMod karma requirements?
The only legitimate ways are: (1) build enough karma to clear the threshold organically, (2) message the moderators and request a manual approval, or (3) use an account that already meets the requirements. There is no technical bypass for properly configured AutoMod rules. Any "exploit" you find online is likely to get your account banned.
What's the difference between a shadowban and an AutoMod removal?
A shadowban affects your entire account across all of Reddit — your posts, comments, and profile are invisible to all logged-out users and most logged-in users. An AutoMod removal affects only a specific post or comment in a specific subreddit. Use the shadowban checker to determine if your account itself is shadowbanned, as opposed to having individual posts silently removed.
Does AutoMod affect comments too?
Yes. AutoMod can be configured to filter or remove comments using the same types of rules — karma thresholds, keyword matching, account age, and more. Comment filtering is slightly less common than post filtering but it exists in many large subreddits. If your comments disappear in the same subreddit where your posts get filtered, your account likely doesn't meet the minimum requirements for that community at all.
Reddit AutoModerator is one of those systems that rewards people who understand how it works and punishes everyone who doesn't. The good news: once you know the rules, you can work within them.
The short version: build real karma, age your accounts, avoid promotional language, and never use URL shorteners. If you need to move faster than organic account-building allows, established Reddit accounts are the professional solution. And if your content keeps getting filtered despite doing everything right, a polite modmail message is always worth sending.
