What is Reddit karma? Reddit karma is the user-reputation system Reddit maintains for every account, tallied from the net upvotes minus downvotes an account has received on its posts and comments over the account’s lifetime. Higher karma signals a longer history of contributions the Reddit community judged as valuable. Lower karma signals either a new account with no history or an account whose contributions have been consistently downvoted. Karma is Reddit’s central credibility metric, and it directly influences what the account can and cannot do across the platform — which subreddits it can post in, how much its content gets throttled by moderators and AutoMod, and how visible its comments and posts become to other users.
Post Karma vs Comment Karma
Reddit tracks karma in two separate categories that appear side by side on every profile. Post karma comes from the net vote score on submitted posts (links, images, text posts to subreddits). Comment karma comes from the net vote score on comments the account has left across the platform. The two numbers are shown independently rather than aggregated, because they signal different things about the account’s contribution pattern.
High post karma with low comment karma usually indicates an account that mostly submits content without engaging in conversation — often a news account, meme account, or link-sharing account. High comment karma with low post karma indicates the reverse — an account that participates in discussions on other people’s posts without submitting much of its own content. Balanced karma across both indicates an account that both contributes original submissions and engages with the community’s conversations, which is the pattern most closely associated with what Reddit reads as a legitimate user.
The distinction matters operationally because automation strategies that build only one type of karma produce accounts with obviously unbalanced profiles. An account that has been running upvote automation without ever posting or commenting will show near-zero karma of either type. An account running only comment automation will show comment karma without post karma. Neither pattern reads as natural, and Reddit users often notice the imbalance when they check the account’s profile before deciding whether to engage.
Why Karma Matters
Low-karma accounts face substantial functional restrictions across Reddit. Many subreddits require minimum karma thresholds before accounts can post — often 10, 100, or 500 karma minimums depending on the subreddit — and accounts that fall below the threshold get their submissions automatically removed by AutoMod. Comment throttling also scales with karma; low-karma accounts have their comments rate-limited more aggressively than high-karma accounts, sometimes to the point of one comment per ten minutes or slower.
The other consequence is visibility. Comments from low-karma accounts often display collapsed by default in threads, requiring other users to actively expand them to read. New comments from low-karma accounts get sorted lower in comment threads regardless of their content quality. Both effects mean that low-karma accounts, even when they produce good content, get seen by dramatically fewer people than high-karma accounts producing the same content would reach.
Karma also feeds into shadowban risk. Accounts that receive downvotes at a rate substantially higher than upvotes get flagged by Reddit’s automated systems as potential spam, and accumulated negative-vote signal is one of the primary inputs to shadowban decisions. Building karma steadily through genuine contributions produces the opposite signal — evidence that the community values what the account posts, which reduces the likelihood of enforcement.
How Karma Is Built
Karma builds through upvotes on submissions and comments, minus any downvotes those items receive. The specific numeric weighting is not linear — Reddit applies vote-fuzzing algorithms that make the exact karma per upvote nondeterministic, but the general pattern is that upvotes add to karma and downvotes subtract from it, and the accumulated total across the account’s lifetime is what shows on the profile.
Different subreddits produce different karma rates. Highly-active subreddits with large audiences produce more karma per successful post because the post reaches more people who can vote on it. Small niche subreddits produce less karma per post but face less competition for attention and often produce more consistent upvote-to-downvote ratios. Balanced karma-building typically involves a mix — contributing to popular subreddits for volume and to niche subreddits for consistency.
Why It Matters for Automation
Reddit automation strategies that skip karma-building produce accounts that hit functional restrictions before they can do any meaningful operational work. Fresh accounts running promotional comments or posts get their submissions auto-removed by subreddit AutoMod configurations that require minimum karma. Fresh accounts running DM outreach get throttled to volumes that make the outreach impractical. Fresh accounts posting external links get shadowbanned within days because low-karma accounts pushing off-platform traffic match the exact pattern Reddit’s spam detection watches for.
The correct sequence for any Reddit automation is to build karma first through passive engagement — upvoting others’ content, occasional low-stakes comments — before introducing any activity that requires credibility. Weeks of karma-building produce accounts capable of running the operational activity the operator ultimately wants. Skipping karma-building produces accounts that never reach operational status regardless of how well the downstream automation is configured.
