Reddit's Contributor Quality Score (CQS), Explained

There's a score attached to your Reddit account that you can't see on your profile, can't look up in your settings, and probably didn't know existed. In many communities it decides whether anyone sees your comments at all.

It's called the Contributor Quality Score, or CQS. If you've ever written a careful, useful reply on Reddit and watched it collect zero votes and zero replies, there's a fair chance it never reached anyone.

This guide explains what CQS is, what it's built from, how moderators actually use it, and what you can do about yours. Everything here is based on what Reddit has published itself. Where Reddit hasn't said something, I'll tell you, instead of passing guesses off as facts.

The short version:

• CQS is Reddit's rating of how likely an account is to be a spammer or a poor contributor.
• Every account sits in one of five tiers: Lowest, Low, Moderate, High, Highest.
• It's built from past actions on your account, network and location signals, account security (like a verified email), and karma.
• Moderators can filter posts and comments by tier, so a low tier can make your contributions invisible in some communities.
• It changes over time. You can raise it.

What CQS is

Reddit describes CQS as a classification created to identify potential spammers and users who are less likely to contribute positively. Every account gets one. Reddit uses it to place users into one of five tiers:

Two details matter more than anything else here. First, you can't see your own tier anywhere in Reddit's interface. Second, scores are updated regularly, and Reddit says accounts move up or down based on their activity and behaviour. A low tier isn't a life sentence.

What CQS is made of

Reddit hasn't published a formula, and probably never will, since a public formula is a manual for spammers. But across its help articles, it has named the kinds of signals that go in. Here's what's confirmed, and what's only rumoured.

Reddit's help article lists three groups of signals: what has happened to your account in the past, network and location signals, and the steps you've taken to secure your account. Its help page for the Reputation filter adds karma and verification to that list.

What you won't find in any of Reddit's own documentation: a mention of account age, VPNs, how many subreddits you post in, or how often you post. Plenty of guides state those as facts. They might matter, but nobody outside Reddit knows.

How moderators use it

This is where CQS stops being abstract. Reddit gives moderators two ways to use it.

1. AutoModerator rules. AutoModerator is the rule engine most subreddits run. It has a contributor_quality field, so moderators can write rules that act on your tier. Reddit's own help article gives three example rules, and they're worth reading closely, because they show exactly how the filter thinks:

# Filter comments from users with under 5 karma in this
# community and a CQS of "low" or "lowest"
type: comment
author:
    combined_subreddit_karma: "< 5"
    contributor_quality: "< moderate"
action: filter

# A karma minimum that "high" and "highest" users skip
type: comment
author:
    combined_karma: "< 20"
    contributor_quality: "< high"
action: filter

# Filter every post from a "lowest" CQS user, regardless of karma
type: submission
author:
    contributor_quality: "= lowest"
action: filter

Notice the second rule. It's a classic karma minimum, except that High and Highest accounts are exempt. A good CQS lets you skip the gates that stop new accounts.

Try it yourself. Change the tier and karma below, switch between a comment and a post, and watch which rules fire.

2. The Reputation filter. Moderators can also switch on Reddit's built-in Reputation filter, a safety setting informed by CQS. It filters content from accounts that look like potential spammers, are likely to have content removed, or are simply unestablished. Moderators choose how strict it is: a "high" setting filters more, a "moderate" setting filters less. It looks at the account doing the posting, not at what the post says.

That last point is the one most marketers miss. A perfect comment from a low-trust account can be filtered before anyone reads a word of it.

The comment only you can see

When a filter catches your post or comment, it isn't deleted. It's held in the moderators' queue until someone approves it, which may be hours later or never. Meanwhile, to everyone else, it simply isn't there.

The cruel part is what you see. Here's the same thread, from your side and from everyone else's.

This is why so many brands conclude that "Reddit doesn't work." They're writing for an audience of nobody, and nothing tells them.

How to check whether it's happening to you: after you post, open the thread in a private browser window where you're logged out. If you can't see your contribution there, it was filtered. Message the subreddit's moderators politely and ask; approval in that community is often all it takes.

How to check your CQS

Reddit doesn't show your tier, but its AutoModerator can read it, so communities have built tools around that. The best known is r/WhatIsMyCQS: you make a post there and an automated reply tells you your current tier.

Two caveats. It's community-run, not an official Reddit feature. And the post stays in your public history, where any moderator who looks at your profile can see you've been checking. Be sceptical of websites that claim to reveal anyone's exact score from a username: CQS isn't something Reddit publishes.

Myths, checked

A lot of what's written about CQS is confident and wrong. Flip the cards.

How to raise your CQS

Since Reddit doesn't publish the formula, nobody can promise a tier. But every confirmed input points the same way, and these steps follow directly from what Reddit has said:

1. Verify your email. It's the only security step Reddit names explicitly, and it takes a minute. Two-factor authentication is a sensible extra step of the same kind, though Reddit hasn't named it.
2. Avoid removals. "Past actions taken on your account" almost certainly includes content removed by moderators and any bans. Read each subreddit's rules before posting, and don't test the limits.
3. Build karma slowly and honestly. Useful comments in communities where you know the subject. Never buy karma or upvotes: vote manipulation is exactly what these systems exist to catch.
4. Be consistent. Regular activity over weeks looks like a person. Twenty comments in an hour on a new account looks like a bot.
5. Keep your network clean. Network and location signals count. If you use a VPN, avoid shared IPs with a bad reputation, and don't run several accounts from the same connection.
6. Give it time. Scores update regularly. The fix for a low tier is a few weeks of good behaviour, not a new account. Creating fresh accounts to escape a bad one can look like ban evasion, which is worse.

What this means for brands

Here's the uncomfortable truth for any company starting on Reddit: a brand-new branded account starts with nothing in its favour. No karma, no history, no track record. In communities that filter by CQS or karma, its first contributions are the most likely to vanish.

That's why the warm-up matters more than the first post. Before your brand account says anything about your product, it should spend weeks being useful: verified, consistent, helpful in communities where you genuinely know the subject. I wrote up the full 90-day version in 10 Reddit Marketing Strategies That Work in 2026.

And it's one more reason fake accounts and bought upvotes are a bad idea in 2026. The systems built to catch spam are now the same systems that decide who gets seen. You can't game your way into a high trust score, but you can earn one.

FAQ

What does CQS stand for on Reddit? Contributor Quality Score: Reddit's rating of how likely an account is to be a spammer or a poor contributor.

What are the CQS tiers? Lowest, Low, Moderate, High and Highest.

Can I see my CQS? Not in Reddit's interface. Community tools like r/WhatIsMyCQS can tell you your tier.

Does CQS change? Yes. Reddit updates scores regularly, and accounts move up or down based on activity and behaviour.

Does every subreddit use CQS? No. Moderators decide whether to use it in AutoModerator rules or turn on the Reputation filter. Many don't.

Why are my comments getting no replies? They may be filtered. Check the thread while logged out. If your comment isn't there, message the moderators.

Can I appeal my CQS? There's no appeal for the score itself. If something you posted is filtered, ask that subreddit's moderators to approve it, and keep building a good history.
