How X Communities Work, and How to Start One.

The short answer

X Communities are topic groups inside X, run by an admin and their moderators. The account that creates one becomes its admin, and that account must be public, at least six months old and carry a verified email address or a phone number. Each Community needs between one and ten rules. Start one only when someone can moderate it every day.

Strategy comes before setup. A Community gives a brand a room it controls inside a feed it does not, and that is the appeal. On X the room is only as good as the people looking after it, and X says plainly that it expects most moderators to be active in their Community every day.

So the real question with x communities is not how to switch one on. It is whether your team can run it, the same question we would ask before opening a Discord server or any other space where people talk back.

What an X Community is

X describes Communities as dedicated spaces for people to connect and share around topics that matter to them. They are started and managed by people on X, not by X itself.

Every Community has three kinds of people:

• the admin, who owns the Community and controls its settings,
• moderators, who enforce its rules and keep the conversation on track,
• members, who post, reply, report posts and invite others where the settings allow it.

To join a Community, an account must be public. X says it is working on expanding availability to protected accounts.

Who can start and run one

X’s help pages say a Community can only have one original creator, and that creator automatically becomes its first acting admin. X sets these eligibility requirements for admin accounts:

1. The account must be public. An account that switches to protected loses its moderator privileges.
2. The account must be at least six months old.
3. The account must have a verified email address or a phone number.
4. The account must not violate, or have a history of violating, X’s Terms of Service.

These are not a one-time check. X says an admin must continuously meet them to remain an admin.

For a brand, that points to one practical choice. Run the Community from an established, public brand account that the team already secures and monitors, not from a new account set up for the purpose, which would fail the six-month rule.

What admins control and what moderators do

The admin owns the Community. X says admins manage the name, rules, cover photo and description, can add moderators from the members list and remove existing ones, and that only admins can change a Community’s settings to open it to anyone.

There is no limit on the number of moderators. X lists their work as:

• inviting and managing members,
• enforcing the Community rules,
• reviewing posts that members report,
• encouraging conversation and setting the tone.

X frames the moderator’s job as three things: facilitating meaningful conversation, connecting like-minded people and developing the Community’s culture. It also says that the more members join, the more content potentially needs moderating.

X does not pay anyone for creating, administering or moderating a Community. For a brand, moderation is staff time, and it should be planned like any other recurring task.

Setting up the basics

X’s moderator playbook sets out the settings every Community carries:

• Name, required, 30 characters or fewer. Names are not unique, so other Communities may share yours.
• Description, required, 160 characters or fewer.
• Theme colour, optional, used on some buttons and highlights.
• Cover photo, optional but recommended, at 1,200 by 480 pixels.

Because names are not unique, the description does more work than it looks. Say who runs the Community and what it is for in the first line, so a visitor can tell yours from a fan group with the same name.

Choosing who can join

The admin picks the membership type. X describes three:

• Open: anyone can tap Join, read the rules and agree to them.
• Ask to join plus member invites: people request to join and moderators approve or deny, and members can invite others.
• Ask to join only: the same request process, with no member invites.

X’s playbook says members of an invite-only Community can invite up to five more people.

There is one firm limit on who you let in. X says admins and moderators must not set any eligibility criteria beyond interest in the Community’s shared purpose, and must never exclude people on protected characteristics such as race, religious affiliation, gender identity, age or disability.

Our view: a restricted Community suits a brand starting out, because it lets the team grow membership at the pace it can moderate. Opening it up is a decision for later, once the rhythm is working.

Writing the ten rules

Every Community must have at least one rule and can have up to ten at a time. Community rules live alongside the X Rules, and X says they must not duplicate, violate or conflict with them.

X offers thought starters, including:

• keep posts and replies on topic,
• be kind,
• no personal attacks,
• no links,
• no advertising or self-promotion.

Ten is a ceiling, not a target. Fewer, sharper rules are easier for members to follow and easier for moderators to apply the same way every time.

Write the rules before launch. X says members are notified whenever a rule is added, changed or removed, even for a punctuation fix, while reordering does not count. A Community whose rules keep changing in its first month sends a lot of notifications. Posts already hidden under a rule stay hidden if that rule later changes or disappears.

The moderation tools

The tools are simple, and that is why the people matter more than the settings.

When a member reports a post for breaking the Community’s rules, every moderator receives a notification. A moderator reviews it and chooses Hide post or Keep. If they hide it, X asks them for feedback on the rule that was broken, so the member understands why.

Moderators can also remove a member, again with feedback on the rule broken, and X notifies the member. Blocking works as a hard line: if an account blocks a moderator, or a moderator blocks an account, that account cannot join, and a current member is removed.

Two queues exist. Moderators handle breaches of the Community’s own rules. Posts that break the X Rules are reported to X. X says moderators need only review and act on posts that may break the Community rules.

What the Community can and cannot keep private

A Community is not a private room. X says Community posts appear on the Community page, in search results, on the poster’s profile and in other timelines, much like ordinary posts. Anyone given the direct link can see a Community’s timeline and a list of all its moderators and members.

Moderators can restrict how non-members engage with Community posts, or hide their replies.

This changes what a brand should use a Community for. It suits open conversation with an audience that already cares, such as product questions or a shared interest. It does not suit anything you would not post on your main account.

How X enforces its rules on Communities

Admins, moderators and members all fall under the X Rules. X says it may act on a single post, on the whole Community or on an account. The options it lists include pausing someone’s role as admin or moderator, requiring edits to a Community’s name, rules, cover photo or description, and suspending a Community temporarily or permanently.

A suspended Community is no longer accessible. Only the admin can appeal.

X also lists ways moderators can misuse their tools: hiding posts or removing members arbitrarily, or in an abusive or disruptive way. A brand moderator who hides every critical post is breaking X’s guidelines, not just annoying members.

When a brand should start one

Start an X Community when three things are true:

1. You have an audience on X that already talks to you and to each other.
2. You have a named person, and ideally a backup, who can be in the Community every day.
3. You have a clear purpose that a 160-character description can state.

Do not start one to manufacture a crowd. X’s own guidance warns against mass invitations to people who may not be interested, and says spamming invites will likely not build a healthy Community.

If you are not sure your team has the capacity, that is the answer. In our view, a Community nobody moderates does a brand more harm than having none. Working out where the hours go before you commit is the kind of problem our social media management team sorts out with brands.

Check one more thing first. You do not have to start the first Community about your brand. Fans can. X allows fan Communities, provided they avoid using the brand’s name in a confusing or deceptive way and say in the description that fans run them.

That makes a quick search worth doing before you launch. X says Community search works on the web and iOS, and is open to accounts that already belong to at least one Community. Not every Community surfaces in results.

What good looks like

A well-run brand Community on X has a short rule set written before launch, a restricted membership that grows with the moderating capacity, and a moderator who posts and replies, not just removes.

X’s own do list is a fair standard: post and engage actively, monitor the reported posts queue, become a recognisable face of the Community, and try to resolve problems with people before hiding a string of posts or removing members.

The test is the same one we apply to community building on YouTube: a smaller room where people talk to each other beats a larger one where nobody does.

Next step

If your team is posting regularly on X but the conversation is not going anywhere, NBK can help find the constraint in the system, and decide whether a Community is the right fix or one more thing to run.
