Reddit AutoMod Simulator

Reddit AutoMod Simulator: predict removal before you post

You hit submit. The post looks great in the comments. Then twenty minutes later it's gone. No notification, no explanation. AutoMod ate it.

The Reddit AutoMod Simulator is a free tool that predicts what will happen to your post before you publish it. Paste your draft and target subreddit, and we'll run the same kind of checks moderators use: rule compliance, account readiness, self-promotion ratio, and tone fit.

How AutoMod actually works

AutoMod is a Reddit-wide moderation bot configured separately by every subreddit's mod team. Common things it checks:

• Minimum karma: many large subreddits require 50, 100, or 500+ karma to post.
• Minimum account age: strict subs block accounts under 30 days old.
• Domain bans: known affiliate or low-quality domains are auto-removed.
• Title requirements: some subs require a question mark, a specific prefix, or a maximum length.
• Self-promotion ratio: Reddit's site-wide guideline is 9:1 (9 community contributions for every 1 self-promotional post).
• Banned phrases: subs add custom blacklists for spammy phrases.
• Link-vs-text restrictions: some subs allow only text posts, or only link posts.

Reddit's AutoMod config is not public. We don't pretend to read it. Instead, we read the subreddit's stated rules, its submission guidelines, and your account's public profile, and we use that to make an informed prediction.

Why was my Reddit post removed?

A post that vanishes without a message was almost always removed automatically. The usual causes, from most to least common:

• The subreddit's AutoMod rules: account too new, not enough karma, a banned word or domain, a missing flair or title tag.
• Reddit's spam filter: a link it distrusts, or a pattern that looks like promotion. The post waits in the moderators' queue, where a moderator can approve it.
• A moderator removed it for breaking a rule. They usually leave a removal reason, but not always.
• Your account is shadowbanned: everything you post is hidden, in every subreddit. The Shadowban Checker tells you in seconds.

If the post is gone in one community and fine in others, it is that community's rules. Message its moderators politely to ask why, and fix the post before posting again.

What the simulator checks

When you submit a draft, the tool runs three layers of analysis:

1. Rule-by-rule match

Every rule on the subreddit is checked against your post individually. For each one you get a status (compliant / warning / violation) and a one-sentence reason that cites the specific part of your post that triggered the verdict.

2. Account readiness

If you provide your username, we pull your public profile and check:

• Karma: total karma vs. typical thresholds.
• Account age: days since signup vs. typical minimums.
• Shadowban status: whether your profile is publicly accessible at all.
• Self-promo ratio: how many of your last 25 posts look promotional. If you're posting a link, we specifically check how often that same domain appears in your recent history.

3. Removal-risk verdict

The tool aggregates the rule checks and account checks into a single verdict: low, medium, or high risk. The verdict comes with a one-sentence summary and a list of concrete fixes you should apply before posting.

Why this matters for marketers

If you're using Reddit to grow a product or a community, removed posts are worse than no posts. They burn your account's reputation with the auto-filter, which compounds over time: repeated removals start triggering Reddit's site-wide spam classifier, which can shadowban you. A 30-second pre-flight check costs nothing and saves the karma, the account, and the time spent writing.

Tips to lower your risk

A few patterns we see repeatedly in posts that get removed:

• Linking to your own domain in the body without a community contribution to balance it.
• Generic title phrasing like "I built a tool" or "Check out my SaaS." These trigger most marketing-skeptical subs.
• Brand-new accounts (under 7 days) posting in any business or marketing subreddit.
• Affiliate URLs, UTM parameters, and tracking redirects that AutoMod's blacklists pick up.
• Posting the same content across multiple subs in a short window (cross-posting flag).

Run the simulator after every edit: small changes (rephrasing the title, removing UTM tags, adding a question at the end) can flip a high-risk post to a low-risk one.

Frequently asked

Does it know AutoMod's actual config for the subreddit? No. That config is private to each mod team. The simulator infers from publicly stated rules, submission guidelines, and your account's posture. Think of it as an educated reviewer, not a perfect oracle.

What if a subreddit has no posted rules? We still check tone, submission guidelines, and your account. Subs without formal rules tend to be permissive but still subject to Reddit's site-wide filter.

Can I check posts for private subreddits? No. The tool only reads publicly accessible subreddit data.

Is my draft saved? No. We don't store your post content; we run the analysis and return results.

Is this free? Yes, no signup required.

Passing AutoMod is the entry ticket, not the win. What makes a post pay off is what happens after it's live: replies, questions, and mentions you'll want to catch while the thread is still moving. Reddit monitoring alerts you when they land, so the post you just pre-flighted keeps working after you hit submit.
