summary: Grow Reddit post-karma and comment-karma safely without bans. Two-phase system: brand-new account (0-30 days, <50 karma) then warmed-up (30+ days, 50+ karma). Avoid 12 specific behaviors that trip automatic moderation. Estimated time to 100 karma: 5-10 days. when_to_use: When operating a new Reddit account for posting, commenting, or promotion. Apply before any posting activity begins.
-
Posting URLs in more than 3 different subreddits within 1 hour → Auto-mod flags as spam, posts removed on sight in heavily-moderated subs (r/news, r/technology, r/worldnews)
-
Replies containing the same URL across 5+ posts in 24 hours → Reddit's spam filter detects "marketing spread" pattern and shadow-bans the URL domain for 7-30 days
-
Account with <10 karma posting links to external sites → Reddit Filter: "域名前科" (domain history) — new accounts posting URLs are queued for manual review 95% of the time
-
Commenting "Great post!" or generic approval phrases on 8+ posts in 1 hour → Auto-mod in r/AskReddit, r/funny flags as "low-effort engagement farming" and removes comments
-
Crossposting the same text to 4+ subreddits simultaneously → Reddit's "brigade prevention" filter detects vote manipulation and locks the post
-
Posting at exact same UTC hour every day for 7+ consecutive days → Bot detection pattern; Reddit labels account as "automated" and rate-limits to 1 post/day
-
Link shorteners (bit.ly, t.ly) in any post or comment → Reddit's spam filter automatically removes links using known shorteners — use the full URL instead
-
Asking for upvotes or using phrases like "please upvote" → Directly violates Reddit ToS; reports from 3 users trigger a Reddit admin review
Goal: Build comment karma without tripping filters. Do not post links yet.
- Create account. Do NOT post anything.
- Spend 20 minutes browsing r/AskReddit, r/CasualConversation, r/ChangeMyView
- Read 15-20 post titles to understand which topics are "hot" (200+ comments indicates active community)
- Find posts in r/AskReddit with 50+ comments where you have genuine expertise
- Write comments that are 2-4 sentences, specific to the post's actual content
- Avoid: one-word replies, "I agree", emoji-only replies, anything that could be copy-pasted elsewhere
- Target: 2-3 substantive comments per day, spread across different hours
- Do not post URLs in these comments yet
- Find a question in r/NoStupidQuestions or r/tipofmytongue that you can answer with a 150+ word response
- Post a text-only self.post (no links). Write like you are explaining to a friend who is not an expert
- If the post gets 5+ upvotes within 2 hours, make one follow-up comment with an additional insight — this signals active engagement
- If the post gets 0 upvotes after 6 hours, do NOT delete and re-post — just leave it and continue commenting
- After reaching 30 comment karma, you may include ONE URL in a text post if it genuinely adds value to your answer
- ONLY post links to: Wikipedia, academic papers, official documentation, or established news sites (BBC, NYT, The Guardian)
- Never link to: your own site, an affiliate page, or any link you control
- Maximum 1 post per 24 hours
- Maximum 10 comments per 24 hours
- Never post between 02:00-06:00 UTC (Reddit's quietest hours = bot traffic is highest = filters are most sensitive)
What unlocks at this stage: trusted-new-user filters expire, posting frequency limits relax, crossposting becomes available.
- Start posting in niche communities with 1,000-50,000 members (r/startups, r/SideProject, r/InternetIsBeautiful)
- Post original text content (your own observations, a tool you built, a question only your experience can answer)
- Include one relevant URL from an authoritative source in the body text
- Respond to every comment on your post within the first 3 hours — fast engagement signals authenticity to Reddit's algorithm
- Post in mid-sized communities (r/technology, r/programming, r/worldnews) — these require some account history
- Use crossposting once per week to reach new audiences without duplicating content
- When including URLs, ensure the page you're linking to is the ORIGINAL SOURCE, not a summary/reblog
- Track which subreddit approves your content fastest: subscribe to that community's mod queue insights by observing your post's removal vs approval rate
- Post to r/RedditSessions or r/CasualConversation to get post-karma which is distinct from comment karma
- Post images/screenshots in addition to text posts (images have a lower barrier to upvote)
- Engage in discussions in your own post threads for 24 hours after posting — this extends the post's "hot" window
- Copy-pasting the same comment across 5+ posts → Reddit Cakeday filter detects "astroturfing" — ban waves sweep these accounts every 2 weeks
- Editing a post after it has 20+ upvotes to insert a URL → Spammy edit detection; Reddit flags this as bait-and-switch
- Replying to your own post with a second account → Vote manipulation = immediate suspension on first detection
- Using the same 3-post template repeatedly → "Karma farm detection" in heavily moderated subs; each template has a unique fingerprint
- Deleting posts that get downvoted, then posting the same content again → Shadow-banned accounts show this pattern; reddit explicitly monitors it
- Linking to Amazon product pages, affiliate sites, or monetized YouTube channels → Reddit's "spam" filter categorizes all commercial links as high-risk
- Posting content that has been posted to the same subreddit in the last 6 months → Reddit's duplicate filter prevents "reposting for karma" and removes within minutes
- Using a VPN or new IP while logged in after 6 months of consistent IP → Account security flags; Reddit may lock the account temporarily
- Punctuation abuse (!!!, ???) or ALL CAPS in titles → Reddit's title quality filter removes these posts automatically before human eyes see them
- Posting to karma-focused subreddits (r KarmaBoost, r FreeKarma4U) for genuine upvote manipulation — Reddit has openly stated these are spam feeds and all accounts participating get flagged
- Mentioning "DM me" or "check my profile for more" → Self-promotion filter catches this phrasing; even if your content is genuine, this phrasing triggers removal
- Replying to controversial posts with a 1-sentence hot take → These attract downvotes fast, and the Reddit algorithm penalizes downvote velocity on fresh content
Step 1: Google Site Search
- Open Google and search:
site:reddit.com "your_username" - If your content appears: you are NOT shadow-banned
- If nothing appears: you ARE shadow-banned
Step 2: The Test Post
- Post a comment on your own brand-new test post using a second browser where you are NOT logged in
- If the comment is visible when logged out but hidden when logged in: shadow-ban confirmed
- If visible in both states: your account is fine
Step 3: The URL Test
- If you previously posted URLs and they were immediately removed (0 upvotes, not shown in search): your domain may be site-banned, not your account
- Fix: stop posting that domain for 30 days, then try again with original content only
