- Most removals come from a subreddit's filters (AutoModerator, reputation filter, Crowd Control), not from a human reading your post
- The removal notice tells you who acted, the community's moderators or Reddit itself, and that decides your next move
- Mod removals get fixed through modmail, Reddit Rules removals get fixed through the appeal link in your inbox
- Never repost the same thing unchanged, fix the cause first or the filter catches it again
Your Reddit post was most likely removed by one of six things: an AutoModerator rule (karma, account age, a keyword or a domain), Reddit's spam filter, a community safety filter like Crowd Control, a moderator enforcing a subreddit rule, Reddit itself enforcing the sitewide Reddit Rules, or a link to a domain the community blocks. The fix depends entirely on which one it was.
Most founders guess, repost, and get removed again. Don't guess. Check who removed it, match the symptom to the cause, and fix the cause before you post anything else.
The six reasons Reddit removes a post
1. AutoModerator rules
AutoModerator is a bot every community can configure. Reddit's Automoderator help page says it can remove or flair posts by domain or keyword, and communities can set minimums for account age, comment karma, post karma and combined karma. Reddit's Poster Eligibility Guide confirms the exact thresholds "aren't disclosed" to deter misuse. So nobody can tell you "you need 50 karma for r/X." Anyone quoting a precise number is guessing.
2. Reddit's spam filter
Reddit's own help page on invisible posts explains that there's a limit to how often people can post and comment in a community. Brand-new accounts with little karma, and newcomers to communities that are sensitive to spam, are the ones who hit it. Mods also train it: when they mark items as spam, the filter learns from them, per the Moderation Queue docs.
3. Safety filters: Crowd Control and the reputation filter
These are switches mods flip, not rules they write. Crowd Control can filter posts from people who aren't trusted members yet. At its strictest setting it catches accounts with negative community karma, new accounts and non-members. The reputation filter filters likely spammers and unestablished accounts, based on Reddit's Contributor Quality Score, which uses karma, verification and other account signals.
4. A moderator removed it for breaking a rule
A human read your post and decided it broke a subreddit rule: self-promotion, wrong flair, off-topic, a repost. This is the most common removal for marketers. Our self-promotion rules guide covers what mods actually tolerate.
5. Reddit removed it for breaking the Reddit Rules
This one comes from Reddit, not the community. Reddit's enforcement and appeals page says its automated systems either send flagged content to human review or, when confidence is high, remove it automatically. When Reddit removes content for a Reddit Rules violation, you're notified of the reason and given instructions to appeal.
6. The link itself
Some communities block specific domains through AutoModerator, and affiliate links are a classic target. Link shorteners, a domain you've dropped across many subreddits, or a brand-new site can all trigger a removal even when your text is fine.
How to tell which one happened
Start with three checks.
- Read the removal notice on your post. Open the post while logged in. Reddit shows you a removal notice, and the wording varies between the app and desktop. What matters is who it names: the community's moderators, or Reddit. Moderators means causes 1 to 4 or 6. Reddit means cause 5.
- Check your inbox and modmail. Mods can send a removal reason as a private message or as a comment on the removed post. Reddit Rules removals arrive in your inbox with an appeal link.
- Look at timing. A removal within seconds of posting almost always means a filter, since no human reads that fast. A removal hours later, after the post got traction, usually means a human moderator.
If nothing is labeled and your post simply doesn't appear for others, your whole account may be affected. Reddit's help center covers accounts flagged for spam, and our shadowban check guide walks through testing it.
Diagnosis table: symptom, likely cause, fix
| Symptom | Likely cause | Fix |
|---|---|---|
| Removed within seconds, new or low-karma account | AutoModerator karma or age threshold, or reputation filter | Build comment karma and history first, then post |
| Removed instantly, established account | AutoModerator keyword or domain rule | Remove the link or flagged wording, ask mods which rule fired |
| Removed instantly in a sub you just joined | Crowd Control or the spam filter | Participate in comments first, become a known member |
| Removed hours later, removal reason attached | Moderator enforcing a subreddit rule | Read the named rule, fix the post, or message the mods |
| Notice names Reddit, inbox message with appeal link | Reddit Rules violation | Use the appeal link, don't repost |
| Posts vanish everywhere, no notice at all | Account flagged for spam | Check account status, follow Reddit's help center steps |
| Text posts survive, link posts die | Domain filter or link-spam pattern | Post without the link, share it only if asked |
How to message the mods
Use modmail, not a chat message to one moderator. Reddit's help page on contacting mods says on desktop you click Message the mods in the Moderators section of the sidebar, and on mobile you tap the overflow menu and pick Message moderators.
Keep it short and specific:
Hi mods, my post "[title]" was removed a few minutes after posting. I read the rules and want to make sure I fix the right thing. Was it caught by a filter, or did it break a specific rule? Happy to edit or drop the link. Thanks.
Three rules for this message:
- Link the post so they don't have to search.
- Ask, don't argue. Reddit's dispute page asks you to be respectful and give the details mods need.
- Wait. Reddit notes that bigger communities can take a while to reply. One follow-up after a few days is fine. Five is how you get muted.
A filter catch is often approved within a day once a mod sees it. If you were banned from the sub rather than just removed, read our guide on getting unbanned from a subreddit.
How to repost correctly
Only repost once you've fixed the cause. Reposting the same thing unchanged is exactly the pattern spam filters are built to catch.
- Fix the account first if thresholds were the problem. Our karma playbook and 10-day warmup plan cover building the history filters look for.
- Use Post Check. Reddit's Post Check uses an LLM to flag potential rule violations while you write. It won't block you from posting, but it shows problems before the mods do.
- Drop the link or move it to a comment only if the sub's rules allow it.
- Match the required flair and format, then read the sidebar one more time.
- Ask before reposting a mod-removed post. Deleting it and posting it again without asking reads as ignoring the removal.
- If the sub is hostile to your topic, move on. Reddit's own dispute page suggests trying a similar community. Our guide to finding subreddits helps.
Where Readyt fits
Full disclosure: we sell a tool. Readyt finds the threads worth joining, drafts replies and posts that respect each subreddit's context, and stops at Copy and send: you read it, edit it and post it yourself. It doesn't post through the API and it can't guarantee a mod won't remove something. What it does is make the careful version the fast version.
FAQ
Why was my Reddit post removed with no reason given?
Most likely a filter caught it, such as AutoModerator, the spam filter, Crowd Control or the reputation filter, and the community didn't set up an automatic removal message. Message the mods through modmail with a link to the post and ask which rule applied.
What's the difference between a post removed by moderators and removed by Reddit?
Moderators act on a single community's rules, and you sort it out with them through modmail. Reddit acts on the sitewide Reddit Rules, notifies you of the reason, and gives you an appeal path. Reddit says you can appeal within six months of the notification.
How much karma do I need to post without being removed?
There's no single number. Each community sets its own karma and account-age thresholds, and Reddit says it doesn't disclose them to deter misuse. Build real comment karma across several communities before posting where it matters.
Can I just delete and repost my removed post?
Not without fixing the cause. The same post from the same account usually hits the same filter, and reposting a mod-removed post without asking can get you banned from the community. Fix the account, the link or the rule issue first, or ask the mods.
