The intent bridge
A draft can avoid an obvious filter and still be the wrong post for the community. Once the copy is safe to review, match it to a subreddit that allows the kind of promotion you need and use a repeatable, human-first workflow.
AutoMod is the invisible gatekeeper between your post and the community. Understanding it is the first step to posting without fear.
AutoModerator evaluates every single post and comment submitted to a subreddit before any human mod sees it. Moderators write YAML config files that define exactly what to look for, and AutoMod enforces those rules instantly, usually within seconds of posting.
There is no single AutoMod config for all of Reddit. Each subreddit's moderator team writes their own rules. A post that sails through r/SideProject may be instantly removed in r/Entrepreneur. That is why testing your post against the specific subreddit matters so much.
When AutoMod removes a post, Reddit often does not send a notification. Your post appears to exist on your end, but other users cannot see it. This is sometimes called a ghost removal. Tools like MediaFast help you write posts that avoid these silent traps before you hit submit.
Moderators write rules in YAML format (a structured text format). Each rule block defines what to check (author karma, title content, post type, domain, etc.) and what action to take (remove, report, flair, ban, or send a message).
A rule can check dozens of conditions simultaneously: account age in days, combined karma, post type (link vs text), title matching a regex pattern, body containing specific phrases, the domain of the submitted link, or even time of day.
Subreddits often stack multiple rule blocks. A post might pass the karma check but fail the keyword filter. Each rule block is evaluated independently, so your post needs to clear every active rule in the config, not just one.
AutoMod does not only remove posts. It can also approve posts automatically, add flair, leave a comment with instructions, report to mods for review, or send a message to the author. Removal is the harshest action, but partial interventions are common.
These figures come from Reddit's own transparency reporting, the official AutoModerator documentation, and peer-reviewed research, not guesses.

This walkthrough covers the same kind of keyword and regex rules the simulator above is trained to detect, including a copy-paste spam filter rule.
These patterns account for the majority of AutoMod removals across Reddit's top marketing and startup subreddits.
| # | Trigger | Fix |
|---|---|---|
| 1 | Account signals in community rules | Confirm the community's current requirements before posting |
| 2 | Keyword or regex match | Rewrite the draft for clarity and remove unnecessary promotional language |
| 3 | Promotional wording | Lead with the community value and disclose affiliation |
| 4 | Link or domain rule | Use the format and destination the rules permit |
| 5 | URL shortener or redirect | Use a transparent canonical URL when links are allowed |
| 6 | Title or body formatting | Use normal sentence case and follow the posting format |
| 7 | Low-context submission | Add the context needed to answer the community's question |
| 8 | Self-promotion rule | Use the designated promotional format or do not post the promotion |
| 9 | Missing post flair | Select the current required flair before submitting |
| 10 | Repost or duplicate detection | Search the community and add a genuinely new contribution |
| 11 | Post type restriction | Use the permitted post type and current schedule |
| 12 | Report or moderation action | Resolve the underlying issue and ask moderators when appropriate |
Knowing which system removed your post tells you exactly what to fix.
These patterns are common categories to inspect, not universal thresholds. AutoMod rules are configured by each community, and a private rule can change the outcome.
| Trigger | Removal Probability |
|---|---|
| Account signal | No universal probability |
| Account age condition | No universal probability |
| Blocked domain | Depends on the configured action |
| Redirect or shortener | Depends on the configured action |
| Affiliate or tracking URL | Depends on the configured action |
| Repeat title pattern | Depends on the configured action |
| Excessive formatting | Depends on the configured action |
| Title regex | A matching rule may remove or review the post |
| Body regex | A matching rule may remove or review the post |
| Post type restriction | Depends on the community format |
| Schedule restriction | Depends on the community schedule |
| Report or review condition | Depends on the configured action |
| Comment cascade | Depends on the configured action |
| Brand or spam blocklist | Depends on the configured action |
| Crosspost restriction | Depends on the destination rules |
Real YAML patterns mods use, followed by a plain-English translation of what each block actually does.
type: submission
author:
combined_karma: "< configured minimum"
action: remove
action_reason: "Karma too low"Plain English: Some communities compare account karma with a local condition. The exact field, threshold, and action are community-specific. Read the current rules and build genuine participation rather than trying to evade the condition.
type: submission
author:
account_age: "< configured age condition"
action: remove
action_reason: "Account too new"Plain English: Some communities compare account age with a local condition. There is no Reddit-wide age cutoff. If a rule applies, comply with it or ask the moderators for the permitted format.
type: submission
url:
domain: ["bit.ly", "tinyurl.com", "amzn.to", "cutt.ly"]
action: remove
action_reason: "URL shorteners not allowed"Plain English: A community may block or review domains, redirects, or referral links. Use a transparent canonical URL only when the current rules permit links, and do not assume a clean URL overrides a self-promotion rule.
type: submission
title (regex): "(?i)(buy now|limited offer|check out my|DM me|link in bio)"
action: remove
action_reason: "Promotional title detected"Plain English: A moderator-defined regex can match wording or structure, but the example is only a teaching pattern. A simulator cannot see private YAML, so revise the draft for clarity and verify the community's current rules.
type: comment
parent_submission:
is_removed: true
action: remove
action_reason: "Parent post removed"Plain English: Some communities configure follow-on actions when parent content is removed. The behavior is not universal, so check the community's help text or ask moderators if a comment disappears with its parent.
Follow the branches to estimate your removal risk before you post.
If the account fails a current community requirement
The account condition may trigger removal or review. Check the exact local rule; there is no Reddit-wide threshold.
If the account is too new under a current local rule
Wait or use the permitted format. Do not try to evade an account-age condition.
If the title or body matches a local promotional phrase or regex
Rewrite the draft around a real question or contribution, then re-check the current rules.
If the destination URL is blocked, restricted, or a redirect
Use a transparent URL only when links are allowed. A clean URL does not override a self-promotion rule.
If the post includes undisclosed affiliate or referral language
Disclose the relationship and follow the community's commercial-link policy, or do not post it.
If the title or formatting violates a local style rule
Use the required title, flair, post type, and formatting for that community.
If the body lacks the context required by the community
Add the details needed to make the post useful on its own, without relying on a click.
If crossposting is disabled or limited in the destination
Create a permitted original submission or choose a community that explicitly allows the format.
If no public rule explains the result
Treat the simulator as an estimate and ask the moderators rather than assuming the post is safe.
If the draft follows the public rules and contributes genuine value
The draft is better prepared, but private rules and human moderation can still change the outcome.
There is no reliable Reddit-wide threshold table. Use these communities as a reminder to read the current rules, not as a shortcut around them.
| Subreddit | Account rule | Age rule |
|---|---|---|
| r/SaaS | Community-specific | Community-specific |
| r/Entrepreneur | Community-specific | Community-specific |
| r/startups | Community-specific | Community-specific |
| r/marketing | Community-specific | Community-specific |
| r/smallbusiness | Community-specific | Community-specific |
AutoMod is powerful but has hard limits. These patterns require human moderators to identify and act on.
A post that tells a compelling founder story while subtly promoting a product reads as genuine content to AutoMod. Only an experienced human mod can spot the promotional intent embedded in narrative framing.
When multiple accounts are controlled by one person to vote and comment in unison, AutoMod sees normal activity. Reddit's anti-vote-manipulation system catches this, but AutoMod's rule engine does not.
A beautifully written post that is completely irrelevant to the subreddit's subject passes every AutoMod rule check. Relevance requires contextual understanding that YAML rules cannot encode.
When an outside group floods a post with coordinated upvotes or downvotes, AutoMod cannot detect the coordinated origin. Human mods must investigate traffic patterns manually.
A post that meets the karma threshold, account age, word count, and formatting rules but adds zero value to the community sails through AutoMod. Quality judgment belongs to humans.
A post asking 'where can I buy this?' is fine in r/findfashion but violates rules in r/frugal. AutoMod cannot interpret the same phrase differently based on subreddit context without explicit regex per sub.
When spammers find a new phrasing pattern that mods have not added to the YAML yet, AutoMod has no way to catch it until the config is manually updated. There is always a lag.
Three anonymized posts, the exact AutoMod signal that caught them, and what would have passed instead.
Original Post
"Just launched [Product] after 6 months of building. Check it out at bit.ly/xyz. Would love your feedback!"
What AutoMod Flagged
Possible triggers include a moderator-defined redirect blocklist and promotional wording. The private rule, if any, determines whether the post is removed, filtered, or sent for review.
What Would Have Passed
Use a transparent canonical URL only if the community permits it, and replace the launch pitch with a specific question or useful lesson.
Original Post
"I started a newsletter about indie hacking. Here is my first issue." (New account with limited community history)
What AutoMod Flagged
A local account-age or participation condition could apply, but the public page does not reveal a universal threshold.
What Would Have Passed
Read the target community's current rules, participate genuinely, and ask moderators which launch format is permitted.
Original Post
"I struggled for years with cold outreach. Then I built my own tool (link in bio). Our product has a discount this week."
What AutoMod Flagged
Possible signals include promotional wording, a referral or discount claim, and a local self-promotion rule. The account history and private configuration determine the actual outcome.
What Would Have Passed
Remove the sales framing, share the useful learning directly, disclose affiliation, and use only the link format the community permits.
Three separate systems operate on every post. Knowing which layer removed you determines how to fix it.
| Layer | What It Catches | Speed | Reversible |
|---|---|---|---|
| AutoModerator | Low karma, new accounts, keyword matches, URL shorteners, affiliate link parameters, regex title patterns, crosspost restrictions, missing flairs | Instant (under 5 seconds) | No. You must repost with a compliant version. |
| Human Moderators | Nuanced self-promotion, off-topic posts, low-value content, community culture violations, ban evasion attempts, sock puppet patterns | Minutes to days depending on mod activity | Sometimes. Polite modmail appeal may restore the post. |
| Reddit Anti-Spam System | Vote manipulation, coordinated brigading, account suspension triggers, shadow bans, platform-wide spam patterns, bulk link posting | Hours to days, often retroactive | Rarely. Account-level actions require a Reddit support ticket. |
Answers to the most common questions about AutoModerator and post removal.
AutoModerator (AutoMod) is a sitewide moderation tool that community moderators configure with rules. Reddit's current documentation says it can send modmail, reply to posts, highlight comments, remove or flair content by domain or keyword, filter content for review, and identify potential spammers or low-quality contributors. Its behavior is community-specific, and the current rules are the source of truth.
When you enter your subreddit and draft post, the tool fetches the subreddit's public description and rules from Reddit's API in real time. It then sends that context plus your post content to an AI model trained on AutoMod YAML patterns. The AI simulates the most likely AutoMod behavior and returns a removal probability score (0-100), a list of triggered rule patterns with severity ratings, a fix suggestion for each trigger, and an AutoMod-safe rewrite of your post.
Common AutoMod patterns include keyword or regex matches, domain and link rules, required words or flair, content filters, and community-specific account signals. Exact thresholds and actions are private to the moderation team, so a simulator can only estimate from public rules and common patterns. Use the result to improve the draft, then confirm the live subreddit rules before posting.
You should not try to bypass AutoMod rules. Subreddits set those rules for a reason, and attempts to evade them can lead to removal or account action. The right approach is to understand which rules you are violating and fix your post to comply with them. This simulator helps you identify possible patterns, then confirm the result against the live rules.
No tool can guarantee the result because AutoMod rules are private configurations that only the subreddit's moderators can see. This simulator uses the subreddit's public rules and description plus common AutoMod patterns to make an estimate. Custom regex, private conditions, human review, and later rule changes may not surface. Treat the prediction as a signal, not a guarantee.
New accounts can encounter community-specific restrictions, but there is no Reddit-wide threshold to rely on. Read the target subreddit's current rules, avoid assuming that a karma or age requirement exists, and build a genuine participation history instead of trying to work around a filter. The simulator can flag patterns, not reveal a private configuration.
