Why Was My Reddit Post Removed?

This is for anyone whose Reddit post disappeared and wants to understand why — whether it's a one-off frustration or a recurring pattern worth fixing before it happens again.

AutoModerator is a bot that individual subreddit moderators configure with their own custom rules to automatically remove posts and comments matching certain patterns. It's the mechanism behind the large majority of removals people encounter, and it acts instantly, without a human reviewing the post first. That's important context: a removal doesn't necessarily mean a moderator read your post and judged it — it often means it matched a pre-set pattern.

• New or low-karma accounts: many subreddits set a minimum account age or comment karma threshold, and posts from accounts below it are removed automatically regardless of content.
• Banned domains or URL shorteners: subreddits commonly blacklist specific domains (often including URL shorteners, since they obscure the destination) to prevent spam and scam links.
• Keyword blacklists: phrases that commonly appear in spam — like asking people to "check my profile" or "DM me" — are frequently blacklisted outright, even in an otherwise legitimate post.
• Missing required flair: some subreddits require every post to carry a specific flair tag; posts without one are removed until the flair is added.
• Posting frequency: posting too often in a short window, even across different subreddits, can trigger frequency-based removal rules aimed at preventing spam.
• Strict title formatting: some communities require specific title formats or tags, and a missing bracket or tag alone can be enough to trigger an automatic removal.

When AutoModerator removes something, it commonly sends the poster a private message or comment explaining which rule was triggered. Checking your Reddit inbox is the most reliable way to find the specific reason for a specific removal — this guide can tell you the common causes in general, but only that message (or a moderator's direct response) can confirm what actually happened in your case.

The Reddit Post Removal Checker can help you check a draft post against common removal patterns before you post it, which reduces the chance of hitting one of these triggers in the first place.

Someone posts a helpful answer in a subreddit that includes a shortened link to a blog post. The post disappears within seconds. Checking their inbox, they find an AutoModerator message explaining that shortened URLs are blacklisted in that subreddit. Reposting with the full, unshortened URL resolves it.

• Posting from a brand-new account without checking the subreddit's account-age requirements.
• Using a URL shortener without knowing whether it's blacklisted.
• Using common spam-adjacent phrases without realizing they're on a keyword blacklist.
• Forgetting required flair.
• Posting too frequently across multiple subreddits in a short window.

Repeated removals in the same subreddit, or a pattern flagged sitewide, can escalate to a subreddit ban or a sitewide shadowban — see how to market on Reddit without getting banned for how that escalation works.

• Check the subreddit's minimum account age/karma requirements, if published.
• Avoid URL shorteners; link directly.
• Avoid common spam-adjacent phrases unless you know they're allowed.
• Add required flair before posting, not after.
• Space out posts rather than posting in quick succession.
