What is a sub-level karma requirement? A sub-level karma requirement is the per-subreddit karma threshold your account has to clear before AutoMod lets you post or comment there. Each subreddit sets its own thresholds independently. r/AskReddit takes accounts with almost no karma. r/entrepreneur wants comment karma above a floor. r/personalfinance wants both post and comment karma at meaningful levels. r/pcgaming wants karma plus 90 days of account age. Nothing about Reddit’s platform enforces a universal minimum — each sub decides its own bar, and the bar’s usually set by whichever mod configured AutoMod when the sub cracked down on spam.

Operators think of karma as one number. It’s not — Reddit tracks post karma and comment karma separately, and most sub-level requirements check the specific type that matters for how the sub gets abused. Subs flooded with low-effort posts filter on post karma. Subs targeted by comment spam filter on comment karma. Some filter on both.

Why sub-level requirements exist

The subs that impose karma requirements are almost always subs that used to get hit hard by spam. A sub with 500k subscribers and no karma filter is target-rich territory — spammers can post promotional content, brigading groups can flood comments, low-quality accounts can dominate the feed. The mod team eventually gets tired of manually removing garbage and configures AutoMod to filter accounts below karma thresholds.

The specific thresholds get set based on what the mod team’s willing to defend. Higher thresholds keep more spam out but also block legitimate new users. Lower thresholds let more legitimate posts through but require more manual mod work. Every sub’s threshold is a judgment call by that sub’s mods, and it changes over time as the spam landscape shifts.

The consequence for operators is that the bar to post in any given sub can be anywhere from zero karma to hundreds — with no consistent pattern, no published list, and no notification when you fail.

How thresholds actually filter your content

Sub-level karma requirements run inside AutoMod. When you post or comment in a sub, AutoMod checks your account’s karma against the sub’s configured thresholds. Below the threshold, your content gets removed instantly — either fully removed or held in the modqueue depending on how the filter’s configured.

The removal is silent. You get no notification. Your post shows up in your own profile as posted but doesn’t appear in the sub’s feed. See the AutoMod Filter entry for the general silent-removal mechanic — sub-level karma requirements are one of the most common filter types AutoMod enforces.

Why fresh accounts hit this wall constantly

Any Reddit account starts with zero karma. Zero karma means every sub with a karma requirement above zero blocks you. That’s most of the useful subs.

Fresh accounts trying to post in serious subs run into the wall immediately. Post to r/marketing on day one with a 5-karma account — filtered. Comment on r/entrepreneur with a 10-karma account — filtered. The account has to build karma somewhere before it can post anywhere useful.

Where you build karma matters. Karma from r/AskReddit and casual subs counts the same as karma from anywhere else — Reddit doesn’t weight karma by source. You can build 500 comment karma in a week by making decent comments in easy subs, then take that karma into serious subs where the karma requirement suddenly no longer blocks you.

This is what Reddit warm-up actually is — building karma in easy subs so hard subs stop filtering you. Skip this phase and every post you make in serious subs gets removed regardless of what the post says.

How to find a sub’s karma requirement

Reddit doesn’t publish sub-level requirements anywhere central. Most subs don’t document them in the sidebar either. Ways to find them:

Sidebar and wiki. Well-run subs post their rules in the sidebar or link to a wiki page with detailed posting requirements. Karma thresholds get mentioned there if the mods bothered to document them.

Message the mods. If your post got removed silently and you can’t figure out why, message the mods asking. Some respond with the specific rule that fired. Most don’t, but the ones that do save you a lot of guessing.

Trial and error. Post from accounts at different karma levels and see which ones clear the filter. This is what most operators actually do — build a mental map of which subs their fleet’s accounts can currently post in based on where posts actually appear.

Third-party AutoMod databases. Some communities maintain shared spreadsheets of sub-level requirements. These are always incomplete and often outdated, but they narrow the search when you’re prospecting new subs.

Building karma efficiently

For fleets of Reddit accounts that need to clear karma thresholds across the board, the fastest path is comment activity in easy subs. Comment karma builds faster than post karma because comments compound — one thoughtful comment on a hot post can pick up hundreds of upvotes over hours, while posts require you to actually create standalone content.

Onimator’s Comment Feeds tool handles this warm-up layer for Reddit accounts. Deploy it against easy subs during the specific warm-up phase, let it accumulate karma over 2-4 weeks, then start pointing the account at target subs where you’ve verified the account now clears the karma requirement.

Why this matters for automation

Sub-level karma requirements are why Reddit warm-up is different from Instagram warm-up. Instagram’s warm-up is about establishing behavioral baseline. Reddit’s warm-up is about accumulating the karma numbers that get you past AutoMod filters. Two entirely different mechanics.

Operators expecting Reddit accounts to be “ready” after a week of activity discover that most useful subs still filter their content because a week of activity doesn’t accumulate enough karma. Accounts that take the karma-building phase seriously — 3-4 weeks of comment activity building up hundreds of karma across both post and comment counters — end up able to post in serious subs. Accounts that rush the phase never get past the filter layer.
