The full setup: the create-community flow, naming, rules, AutoModerator basics, appointing moderators, styling, and the seeding work that takes a new subreddit from empty to active.
Quick answer: Click your profile icon, choose "Create a community," pick a permanent name and a community type, then set rules, AutoModerator, and styling before inviting anyone. Reddit does not publish an exact karma or account age number required to create a subreddit, per its own FAQ wiki, but the option only appears once your account has real history and is in good standing.
Daily active users (DAUq) in Q1 2026, up 17% year over year, per CNBC. A new subreddit is competing for attention inside that pool.
The example account_age threshold shown in Reddit's AutoModerator documentation. Individual subreddits set their own value, Reddit does not fix one platform-wide.
The floor comment_karma cannot fall below, per the same AutoModerator documentation, so a downvote pile cannot spiral an account's karma forever.
Searches for subreddit creation requirements often expect a specific karma number or account age in days. Reddit does not publish one. Its FAQ wiki describes karma and account standing in general terms, not as a fixed threshold for creating a community. What is consistently true across accounts: it needs real activity history and to be in good standing, not suspended, not brand new. Treat any specific number you see quoted elsewhere as an estimate, not an official rule.
Do these roughly in order. Skipping the rules, AutoMod, or seeding steps is why so many new subreddits stall within the first month.
Confirm your account is eligible before you start. Reddit does not publish an exact karma or account age number for creating a community, per its FAQ wiki, but an account needs real history and to be in good standing. If "Create a community" is missing from your menu, keep participating for a while and check again.
Click your profile icon and choose "Create a community." This starts the official flow on both desktop and the mobile app, and the option only appears once your account meets Reddit's unpublished eligibility bar.
Pick a name you cannot easily change later. Names run 3 to 21 characters using only letters, numbers, and underscores. Search for near-duplicate names first so members are not confused about which community they landed in.
Choose the right community type. Public lets anyone view and post, Restricted lets anyone view but only approved users post, and Private is invite only. Most niche and brand communities should start Public.
Mark whether the community is 18+ and set the initial topic tags so Reddit can surface it in search and recommendations to people already interested in that subject.
Write specific rules and publish them to the sidebar or About panel. Vague rules like "be nice" cannot be enforced consistently. Specific rules that describe what belongs and what gets removed give both members and AutoModerator something concrete to check against.
Add a wiki page for anything you do not want to repeat constantly, self-promotion policy, posting days, required formatting, and link it from the sidebar so it is visible before someone posts.
Configure AutoModerator with basic conditions like account_age and comment_karma. Per Reddit's AutoModerator documentation, these conditions let the bot hold or remove posts from very new or low-history accounts before a human ever sees them.
Style the community: upload an icon and banner, set brand colors, and create post flairs that cover the common post types you expect. A styled subreddit reads as active and intentional rather than abandoned.
Add one or two trusted co-moderators and personally seed and invite the first members. A subreddit with zero posts and one moderator looks dead. Seed content yourself and invite people who already care about the topic before opening it up widely.
Once your subreddit has its first regular posters, MediaFast can help you keep the seed posts coming so the feed stays active instead of going quiet between your own updates.
This is set during creation and can be changed later, but getting it right up front saves a confusing switch after members join.
| Type | Who sees it | Who can post | Best for |
|---|---|---|---|
| Public | Anyone | Anyone with an eligible account | Most niche topics, brand communities, and anything meant to grow beyond your first invite list. |
| Restricted | Anyone | Only users the moderators approve | Curated, higher-quality communities where you want broad readership but tight control over who posts. |
| Private | Invited members only | Invited members only | Small working groups, internal teams, or communities that are not meant to be discovered publicly. |
The name gets locked in the moment members start joining and linking to it. These are the considerations worth ten minutes before you type anything into the create-community form.
| Consideration | Why it matters |
|---|---|
| Length and characters | Names run 3 to 21 characters, letters, numbers, and underscores only. No spaces, no hyphens, no special symbols. |
| It is effectively permanent | Reddit does not offer a simple rename for an existing subreddit. Treat the name as a one-time decision, not a draft you will tidy up later. |
| Search for near-duplicates first | A name that is one character off from an existing subreddit confuses new members and can quietly siphon traffic meant for you. |
| Match your brand name if you have one | Consistency across Reddit, your site, and other channels makes the subreddit easier to find when someone already knows your product. |
| Avoid trend-chasing names | A name tied to a fad or a version number ages awkwardly once the trend passes, and it is not one you can quietly change later. |
| Say the name out loud | Names that are clean written down sometimes read as an unrelated word or an awkward abbreviation once spoken, which matters when people recommend it verbally. |
Per Reddit's AutoModerator documentation, these are the conditions new moderators configure most often. Setting even a couple of these before launch removes a large share of the spam a brand new subreddit would otherwise see manually.
| Condition | What the docs say | How it is used |
|---|---|---|
| account_age | "compare to the age of the author's account" | Example from the docs: account_age: < 60 hours blocks accounts created less than 60 hours ago. |
| comment_karma | "compare to the author's comment karma (note that comment karma will not go below -100)" | Used to filter accounts with little or no history of genuine participation. |
| domain | "the submission's domain" | Lets mods allow or block specific link domains, including subdomains of a blocked domain. |
| title | "the submission's title" | Matches keywords or phrases in the post title, often used to catch spam wording automatically. |
| body | "the full text of the post" / "the full text of the comment" | Checked on text posts and comments, used for keyword filters and required disclosure text. |
These conditions are configured per subreddit by the moderators who set them up, not fixed by Reddit itself. There is no single "correct" account_age or comment_karma value. Start with something modest, watch what gets caught over the first few weeks, and adjust from there.
Work through this before you open the subreddit up to strangers, not after the first spam wave arrives.
Rules written specifically, not vaguely, and visible in the sidebar or About panel.
AutoModerator configured with at least account_age and comment_karma conditions.
At least one co-moderator added, ideally in a different time zone than you.
Post flairs created for the common content types you expect in the community.
A wiki page covering self-promotion or spam policy, linked from the sidebar.
Modmail checked on a schedule so genuine questions do not sit unanswered for weeks.
The creator is automatically the first moderator, but nobody else is added unless you do it deliberately. These are the traits worth screening for before handing someone the permissions.
Available at different hours than you
A co-moderator in a different time zone closes the gap where spam and rule-breaking posts would otherwise sit unreviewed overnight.
Already an active, genuine participant
The best early co-moderators are usually people already posting and commenting well in the community, not outside recruits with no history there.
Comfortable enforcing rules consistently
Someone who avoids conflict will let obvious rule violations slide, which erodes the rules for everyone else who is following them.
Willing to learn AutoModerator and modmail
Moderating is more than approving posts. Understanding the tools well enough to adjust them is what actually distributes the workload.
A new subreddit does not launch with sensible defaults already in place. It launches empty, and every setting below is on you to configure.
You are the only moderator, and nothing is configured yet
A brand new subreddit has default settings: no custom rules published, no AutoModerator conditions set, no flair created, and default (often plain) styling. None of that happens automatically.
The subreddit is immediately visible if set to Public
Even with zero posts, a Public subreddit can show up in search and be joined by anyone. There is no "draft mode" that hides it while you finish setup, so work through the checklist quickly.
Default post types are usually all enabled
Text, link, image, and video posts are typically all allowed until you restrict them in community settings, which is worth revisiting once you know what content the community should actually contain.
Discovery settings are separate from community type
Whether the subreddit shows up in Reddit's own recommendations and search is a distinct setting from Public, Restricted, or Private, and is worth checking rather than assuming.
These live in community settings rather than the create-community form itself, but they are worth deciding on deliberately in the first week rather than leaving on default.
| Setting | What to decide |
|---|---|
| Allowed post types | Whether text, link, image, video, and poll posts are all enabled, or whether the community works better restricted to one or two formats. |
| Spoiler tag | Whether members can mark a post as a spoiler, useful for subreddits built around shows, games, or ongoing releases. |
| NSFW tag | Whether the community as a whole, or individual posts, need an 18+ marking based on the content you expect. |
| Comment sort default | Whether new visitors see comments sorted by Best, Top, or New by default, which quietly shapes what conversation looks most prominent. |
| Crossposting | Whether other communities can crosspost your posts into their own subreddit, which can help or hurt visibility depending on your goals. |
A styled subreddit signals that someone is actually running it. Default gray and white reads as abandoned even when the creator is active behind the scenes.
Community icon
A small, recognizable icon that reads clearly even at the tiny size Reddit displays it in feeds and search results.
Banner image
A wider banner that states the topic at a glance. This is often the first thing a new visitor actually looks at before reading anything else.
Brand colors
Custom accent colors applied through the community styling settings, used consistently across flair, buttons, and highlighted text.
Post flairs
Tags members choose or that moderators assign to categorize posts, often required before a post is allowed to stay up.
Sidebar widgets
Shortcut links to rules, the wiki, related communities, and any recurring threads, all visible without a new member having to ask.
Creating a subreddit takes minutes. Getting the first genuine members is the part that actually determines whether it survives.
Seed content before inviting anyone
A subreddit with zero posts looks abandoned. Post genuinely useful content yourself first so the first real visitors see an active feed, not an empty shell.
Invite people who already care, personally
A direct, personal invite to someone already active in a related space converts far better than a public promotional post asking strangers to join.
Cross-promote with permission, not spam
Ask moderators of related communities before linking your subreddit there. One legitimate mention in front of the right audience beats dozens of unsolicited drops.
Reply to everything in the early weeks
Early members are watching to see if anyone is home. A moderator who replies to every post and comment signals the community is actually active.
Keep posting consistently, not in bursts
A steady drip of quality posts sustains momentum better than a flurry of activity followed by silence. Tools like MediaFast can help keep that stream of ideas going once the basics above are in place.

Reply to every post and comment in the first weeks
Add a co-moderator earlier than feels necessary

Launching with an empty feed
Writing vague rules like "be nice"
Leaving AutoMod unconfigured at launch
Guessing at an exact karma number to promise members
Spamming invites in unrelated subreddits
Ignoring posts and modmail for weeks
Moderating entirely alone past the first month
Skipping the sidebar and wiki setup
Launching with zero seed posts. A brand new subreddit with an empty feed gives visitors no reason to stay or post themselves. Seed it yourself first.
Picking a niche that is too broad. A subreddit that tries to cover everything in a category rarely develops its own identity. Narrower, specific niches are easier to moderate and easier for members to understand at a glance.
Leaving AutoModerator unconfigured. Without account_age or comment_karma conditions set, spam and low-effort posts from brand new accounts land directly in front of real members instead of being held automatically.
Writing vague rules like "be nice." Rules that cannot be pointed to when removing a post are rules that will not be enforced consistently, which frustrates members on both sides of a removal.
Skipping the wiki and sidebar setup. Members cannot follow a self-promotion policy or posting format they never saw. Publish it before you need to enforce it, not after the first violation.
Moderating entirely alone. One moderator across every time zone means gaps where spam and rule violations sit unaddressed for hours. Add a co-moderator earlier than feels necessary.
Guessing at an exact karma number to hit. Reddit does not publish one, and repeating an invented figure to new members sets an expectation that is not actually how eligibility works.
Disappearing after the first week. A moderator who stops posting and replying once the initial excitement fades is the single most common reason new subreddits stall under a few dozen members.
A topic-specific community with its own name, rules, and moderators, denoted with an r/ prefix.
A user with permissions to manage a subreddit's rules, remove content, and configure tools like AutoModerator. The creator becomes the first mod automatically.
Reddit's rule-based bot that moderators configure to automatically remove, hold, or flag posts and comments matching conditions like account_age or comment_karma.
The rules and description panel for a subreddit, where most posting rules and links to the wiki are published.
An editable page tied to a subreddit, commonly used for detailed rules, self-promotion policy, or FAQs that do not fit in the sidebar.
A tag attached to a post or a user, often required by subreddit rules to categorize content before it is allowed to stay up.
Reddit's messaging system for contacting a subreddit's moderator team directly, the right channel for asking about an ambiguous rule.
The holding area where posts and comments AutoMod flags, or that other users report, wait for a human moderator to review.
A running count of net upvotes minus downvotes on a user's posts and comments, tracked separately as link karma and comment karma.
The visibility and posting setting chosen at creation: Public, Restricted, or Private, changeable later from community settings.
Writing rules, configuring AutoModerator, and then keeping a new subreddit's feed active are three separate jobs. MediaFast handles the last one, generating the steady stream of quality posts a new community needs once the setup above is done, so the feed does not go quiet between your own updates.
MediaFast generates quality Reddit posts in seconds, giving your fresh community the content it needs to grow past the stall-out point.

Setup, requirements, moderation, and the realistic growth timeline.
Sign in to Reddit with an established account, then click your profile icon and choose "Create a community." Pick a unique name (letters, numbers, underscores, 3 to 21 characters), choose a community type (Public, Restricted, or Private), mark whether it is 18+, then click "Create community." You become the first moderator automatically and can add rules, flair, styling, and AutoModerator from there.
Reddit does not publish an exact karma number or account age required to create a community. Its own FAQ wiki (old.reddit.com/wiki/faq) describes karma and account standing in general terms rather than listing a hard threshold for community creation. What is consistently true: the account needs to be established and in good standing, not brand new, and not currently suspended. If "Create a community" is missing from your menu, keep genuinely participating in existing subreddits and check again later rather than guessing at a specific number.
Yes, but keep expectations realistic. Brand subreddits (r/YourCompany) work well as support communities for existing customers, but Reddit users often treat brand-owned subs as advertising and avoid them. A more durable approach for most businesses is staying active in existing industry subreddits while running a niche-topic community that naturally connects to the product without being a billboard for it.
There is no fixed timeline Reddit publishes, and it varies enormously by niche. Realistically, the first wave of members comes from active seeding: posting your own quality content and personally inviting people who already care about the topic. Momentum tends to compound once a subreddit has enough regular posters that it no longer depends on the founder alone. Most new subreddits stall not because growth is inherently slow, but because the creator stops seeding content too early.
Successful subreddits share a few traits: a niche that is narrow enough to feel distinct but broad enough to sustain regular posts, moderation that enforces clear rules without being heavy-handed, active seed content from the moderators in the early months, and visible rules plus a sidebar or wiki that sets expectations before someone posts. Subreddits that stall usually lack one of those: a tight niche, active moderation, or consistent early seeding.
No experience is required. When you create a subreddit you automatically become its first moderator with full permissions. Moderating is still real, ongoing work: expect to spend time reviewing the mod queue, answering questions, and enforcing rules, especially in the first months. Adding a couple of trusted co-moderators early helps distribute that work.
Yes, within limits. Mentioning your subreddit naturally when it is relevant in another discussion, linking it from your profile bio, or linking it from your own external channels is generally fine. Spamming subreddit invites across unrelated threads, or posting the same promotional message repeatedly, is what gets accounts and subreddits flagged. Reddit's own self-promotion guidance frames this as a ratio you police yourself, not a hard platform-enforced limit.
Start small, with one to three trusted moderators. Adding too many people too early creates friction and slows decisions. As daily activity grows, add moderators in proportion to that activity rather than on a fixed schedule. Coverage across different time zones tends to matter more than raw headcount for catching spam and answering modmail quickly.
Open the official Reddit app (iOS or Android), tap your profile icon, and choose "Create a community" (sometimes labeled "Create a subreddit"). Enter a name, pick a community type, toggle the 18+ flag if it applies, then tap "Create community." Your account still needs to be established and in good standing, the same as on desktop. If you do not see the option on mobile, your account likely does not yet meet Reddit's (unpublished) eligibility bar.
The flow is identical on both: open the Reddit app, tap your avatar, choose "Create a community," fill in the name and type, and tap Create. Many moderators still prefer desktop for the detailed setup afterward, wiki pages, AutoModerator rules, banner and flair styling, since some of those tools are easier to reach on reddit.com than inside the app.
Open the Reddit app, navigate to the subreddit, and tap the "+" or "Create Post" button. Choose a post type (text, image, link, poll, video), write a title, add your content, select flair if the subreddit requires it, then tap "Post." Check the subreddit's "About" tab for its specific rules first, since many communities require flair or have posting restrictions that are not obvious from the feed.
Type "r/" immediately followed by the subreddit name with no space, for example r/Entrepreneur. It automatically becomes a clickable link on both mobile and desktop. To tag a user, use "u/" followed by their username. Both work in post titles, post bodies, comments, and DMs, but not inside images or video.
Yes. Open the subreddit, tap the three dots near the join button, and choose "Mute community." That removes it from your feed, r/all, r/popular, and Home recommendations without unsubscribing you outright. There is no separate "delete from existence" option, but muting has the same practical effect for your own account. To reverse it, return to the subreddit and tap "Unmute."
Mute individual subreddits from their three-dot menu, or go to Settings, then Feed, and toggle "Show NSFW content" off to hide all 18+ communities at once. Both are official Reddit controls. Muting only affects discovery feeds and recommendations, not a direct link someone shares with you outside those feeds.
