You opened a subreddit, found a discussion you wanted to join, typed a thoughtful response, hit Comment — and Reddit blocked it with a message about your comment karma being too low.
This isn’t a ban. It’s a threshold. The subreddit’s moderators set a minimum karma score to keep out bots, spammers, and brand-new accounts. Your job is to prove you’re not one of those.
But you don’t need to grind for weeks. You need a system.
What you’re trying to do: get your comment karma above the subreddit’s hidden threshold so your comments actually appear in the discussion. It’s not about hitting a magic number like 100 or 500 — it’s about understanding which subreddits have low thresholds, then building visible, useful comment history that makes your account look legitimate.
Step 1: Check your real numbers first
Before you do anything, find out where you stand. Reddit doesn’t show your karma split by default, but you can check it easily.
Open your profile and look at your total karma. Then click on your profile name on old Reddit (old.reddit.com/user/yourname) or check the “About” section on the mobile app. You’ll see two numbers: post karma and comment karma.
Why this matters: some subreddits require comment karma specifically, not total karma. If your total looks fine but you’re still blocked, it’s because your comment karma is the problem. If your profile shows 50 post karma and 3 comment karma, you know exactly what to build.
You also want to check your account age. Reddit karma requirements often work alongside account age filters. A 3-year-old account with low comment karma will get through more gates than a 3-day-old account with the same karma.
Step 2: Find subreddits with no or low karma requirements
You can’t build comment karma in subreddits that block you from commenting. So you need a starting point.
Look for:
- Large default subreddits like r/AskReddit, r/funny, or r/pics. These usually don’t enforce karma gates because they get too much traffic to filter every commenter.
- New or small subreddits (under 10,000 members). They want activity and rarely set high thresholds.
- Subreddits for beginners like r/NewToReddit. They exist specifically to help new users understand karma and often have no minimum requirements.
Avoid subreddits with strict posting rules (like r/technology or r/science) until your karma is solid. The message “comment karma too low” means you’re wasting time there for now.
Step 3: Write comments that earn upvotes — but don’t farm
Here’s the mistake most people make: they go to r/AskReddit and write “LOL” or “Same” a hundred times. That doesn’t work. Low-effort comments get ignored or downvoted, and downvotes make your karma worse.
Instead, follow this pattern:
- Answer the actual question. If someone asks “What’s the worst purchase you’ve ever made?” give a specific story. Detail gets upvotes.
- Add something to an existing thread. Find a comment with a few upvotes and reply with a relevant follow-up, a related experience, or a correction. Threads are where visibility lives.
- Sort by “rising” or “new” in bigger subreddits. Early comments on posts that blow up get disproportionate upvotes.
- Keep it readable. One or two short paragraphs. No walls of text.
The goal is to get 10-20 upvotes per comment, not 500. You need steady, small gains across a few days.
Step 4: Fix the invisible-comment problem
Sometimes your comment goes through but nobody sees it. This is the “shadow-filtered” problem — the subreddit’s automod removes your comment silently because of your low karma.
How to check: open your profile in an incognito window or log out and look at your comment history. If your comments show up for you but not when logged out, they’re being filtered.
The fix: contact the subreddit’s moderators via modmail. Be honest: “I’m a new user trying to participate. My comments seem to be getting removed. Is there a karma threshold I need to meet?” Most mods will tell you the exact number or approve your comments manually. This is the fastest way to get an exact requirement without guessing.
Step 5: Scale up once you hit 50-100 comment karma
At around 50 comment karma, most basic gates open. At 100, almost all subreddits will accept your comments. But you should still be mindful of your account’s overall reputation.
Account reputation matters more than the raw number. If you have 100 comment karma from 2 massive comments, that looks different than 100 comment karma from 20 real interactions. Subreddits with manual review (not just automod) will check your history. A visible, consistent history of helpful comments is worth more than a spike.
If you’re building an account for marketing or outreach purposes, remember that account age and visible comment history are part of the trust equation. A brand-new account with 200 comment karma still looks suspicious. A few weeks of steady, honest participation builds the kind of reputation that passes manual checks.
Practical example: from 5 comment karma to posting in 3 days
Here’s a realistic scenario.
Day 1: You have 5 comment karma. You go to r/AskReddit, sort by “rising,” and answer three questions with personal stories. One gets 40 upvotes, one gets 12, one gets 3. Your comment karma jumps to ~60.
Day 2: You target r/smallbusiness (low threshold) and write a detailed response to someone asking about pricing strategies. It gets 25 upvotes. You also reply to two threads in r/NewToReddit with helpful answers. Your comment karma hits ~90.
Day 3: You test the subreddit that originally blocked you. Your comment goes through. The gate has opened.
The key wasn’t speed. It was picking subreddits with low requirements, answering real questions with real value, and using the “rising” sort to get early visibility.
Common blockers and fixes
| Blocker | Why it happens | Fix |
|---|---|---|
| Comments removed silently | Automod karma threshold | Ask mods for the exact number |
| Downvoted into negative | Low-effort or off-topic comments | Stick to threads where you have genuine input |
| Can’t comment at all | Subreddit has strict minimums | Use the starter subreddits listed above |
| Posts removed despite high comment karma | Post karma requirement is separate | Build post karma in the same subreddits |
| Shadowban (all comments removed everywhere) | Account flagged by Reddit’s filters | Message the Reddit admins to appeal |
Quick action checklist
- Check your comment karma vs post karma split
- Check your account age
- List 3-5 subreddits with no/low karma requirements
- Sort by “rising” and write thoughtful answers
- Check if your comments are visible when logged out
- Contact mods if you suspect silent removal
- Keep building until you hit 100 comment karma
- Test your original target subreddit after 2-3 days
Practical takeaway
The “comment karma too low” message isn’t a wall — it’s a filter. It exists to keep out throwaway accounts and bots. Once you understand the mechanics (specific karma types, subreddit thresholds, and the value of visible history), you can move past it in a few days without gaming the system.
Focus on real participation in accessible subreddits, check your numbers, and use modmail when you’re stuck. And if you’re building an account for long-term use, treat comment karma as the foundation. It’s often more valuable than post karma for credibility because it shows you actually participate in discussions, not just submit links. A well-warmed account with steady comment history will pass more gates than a new account with a one-time karma spike.
For readers comparing Reddit account options, researching buy Reddit accounts should include account history, niche fit, realistic activity, and reputation rather than choosing only by price.
For this use case, practical proxy option for Reddit workflows should be compared by pricing, setup difficulty, support quality, refund policy, and whether it fits your workflow.
FAQ
Q: What does “comment karma too low” actually mean?
A: It means the subreddit you’re trying to comment in has an automod rule that removes comments from accounts below a certain comment karma threshold. The threshold is set by the subreddit’s moderators and can range from 1 to several hundred. It’s not a Reddit-wide rule — it’s specific to each community.
Q: How much comment karma do I need before I can comment anywhere?
A: There’s no universal number. Some subreddits have no requirement at all, while strict communities require 100-500 comment karma. As a rule of thumb, 50 comment karma opens most standard gates, and 100 covers nearly all subreddits. If you’re blocked after that, contact the mods to ask for the exact threshold.
Q: Can I just buy Reddit accounts with high comment karma instead of building it myself?
A: You can buy Reddit accounts with established comment karma and visible history, but you need to evaluate them carefully. Check the account age, the quality of comment history, and the niche fit. A purchased account should still be warmed up gradually — changing your IP, browser profile, or email too quickly can flag it. For outreach or marketing workflows, a ready account with real comment karma can save weeks of warm-up time, but it’s not a shortcut to guaranteed posting rights.
Q: Does post karma help with the “comment karma too low” message?
A: No. The message is specifically about comment karma. Post karma and comment karma are tracked separately. A user with 1,000 post karma and 5 comment karma will still be blocked from commenting in subreddits that require comment karma. You need to build comment karma specifically through comments.
Q: My comments get upvotes but my karma isn’t increasing. What’s wrong?
A: Upvotes on your comments should increase your comment karma, but there’s a delay — Reddit updates karma with a lag that can be several hours. Also, if some of your comments are being removed by automod, they may not count. Check your visible comment history while logged out, and wait 24 hours before assuming something is broken.
