What Are Blocked Words on YouTube? Complete Creator Guide

Blocked Words

Blocked Words is a channel-level YouTube moderation list containing words and phrases the creator does not want to appear publicly without review.

Comments containing or closely matching blocked terms may be held in YouTube Studio for up to 60 days. Matching live chat messages are blocked, and the same words can apply to viewer posts in a YouTube Community.

Where Do Blocked Words Apply?

• Comments across the creator's videos and Shorts
• Comments on the channel homepage and posts
• Live chat messages
• Viewer posts in the channel's YouTube Community
• Clip creation titles or text where YouTube applies the channel's blocked terms

YouTube's current system does not allow a blocked-word list to apply to only one specific video.

What Happens to a Matching Comment?

A comment containing or closely matching a blocked term may be placed in the Held tab instead of publishing publicly.

The creator can:

• Approve the comment
• Remove it
• Report it
• Hide the commenter
• Leave it unpublished until the held period expires

What Happens in Live Chat?

YouTube says live chat messages containing or closely matching blocked words are blocked rather than sent to the ordinary published comment queue.

Creators should test the list before a major live event because an overly broad term can block legitimate discussion instantly.

What Happens in YouTube Communities?

Blocked words and blocked links established for comments also apply to viewer posts in the creator's Community.

Managing Community moderators can manage blocked words; standard moderators have narrower authority.

How to Add Blocked Words

1. Open YouTube Studio.
2. Select Settings.
3. Open Community moderation or the current Content controls section.
4. Find Blocked words.
5. Add the words and phrases the channel needs to review.
6. Save the settings.

The location can differ between computer and the YouTube Studio mobile app as YouTube updates its Community moderation interface.

Words vs. Phrases

The list can include individual words and multi-word phrases. Phrase entries are useful when a harmless word becomes problematic only in a specific expression.

Use the narrowest term that addresses the real problem. Blocking a broad word can create many false positives.

What Does "Closely Matching" Mean?

YouTube says it may hold or block content that contains or closely matches a listed term. It does not publish the full matching algorithm.

Matching may account for variations, but creators should not treat the system as a precise regular-expression engine or assume it detects every misspelling, symbol substitution, or language variation.

Are Blocked Words Case-Sensitive?

YouTube does not document the list as a case-sensitive programming filter. Creators should not create duplicate upper- and lowercase entries unless testing shows a specific need.

Review the Held tab to learn how the current system treats actual audience language.

Blocked Words vs. Basic and Strict Moderation

Feature	Blocked Words	Basic or Strict
Input	Creator supplies terms	YouTube's systems identify potentially inappropriate content
Purpose	Channel-specific language and spam patterns	Broader automated moderation
Precision	More controllable but can be overbroad	Adaptive but may hold unexpected comments
Best use	Names, slurs, scams, recurring phrases, and channel-specific abuse	General spam and inappropriate-content protection

The features can be used together.

Blocked Words vs. Blocked Links

Blocked Words targets text terms. Blocked Links holds comments containing URLs and blocks URLs in live chat.

A link may be held even when it contains no blocked word, and a text comment may be held even when it contains no URL.

Blocked Words vs. Hidden User

Control	Scope	Review Available?
Blocked Words	Matching content from ordinary users	Matching comments can be reviewed in Held
Hidden User	All comments, live chats, and Community posts from the user and associated accounts	Hidden-user comments do not appear in Studio for review

Approved User Exception

Comments from approved users publish automatically and are not filtered for blocked words, blocked links, or potentially inappropriate content.

This is a powerful exception. Only approve viewers whose future comments the channel is prepared to publish without those automated checks.

Are Existing Comments Affected?

Adding a blocked term is primarily a rule for future comments and messages. YouTube's documentation specifically identifies hiding a user and turning comments off as actions that affect existing comments.

Do not expect a newly added word to retroactively search and remove every older comment containing that term.

How Long Are Matching Comments Held?

YouTube can hold them for up to 60 days. After that period, an unapproved held comment may no longer remain available for review.

Review Held comments regularly if legitimate comments matter to the channel.

Words to Consider Blocking

• Slurs and targeted harassment terms
• Recurring scam phrases
• Impersonation contact details
• Repeated cryptocurrency or investment spam
• Personal information that should not be posted
• Names involved in active harassment
• Off-topic promotional slogans
• Common misspellings used to evade an important blocked term

Do not blindly paste a generic profanity list without considering the channel's language, audience, and context.

Words That Can Cause False Positives

• Short words contained inside unrelated words
• Common names
• Product names
• Words used both positively and negatively
• Technical terms
• Geographic names
• Words central to the channel's educational topic

Multilingual Channels

A blocked list should reflect the languages and spelling patterns used by the audience.

Consider:

• Common translations
• Transliterations
• Regional slang
• Accent and punctuation variations
• Homoglyphs and symbol substitutions

YouTube can detect close matches, but the creator should still monitor missed and incorrectly held content.

Blocked Words and Criticism

The list should target abuse, scams, or disruptive patterns—not ordinary disagreement.

Blocking every negative term can:

• Hide useful corrections
• Create distrust
• Make troubleshooting harder
• Prevent customers from describing a problem
• Produce a misleadingly positive comment section

Using the Held Queue to Improve the List

1. Review which term appears to have triggered the hold.
2. Approve legitimate comments.
3. Remove true abuse or spam.
4. Replace broad terms with narrower phrases.
5. Add recurring evasion patterns.
6. Document important changes for moderators.

Managing Moderators and Blocked Words

YouTube's current permission table allows managing moderators to add, remove, or copy the blocked-word list. Standard moderators cannot manage the list.

Because changes affect the whole channel, only trusted moderators should receive that authority.

Blocked Words and Clip Creation

YouTube notes that blocked words also cannot be used when viewers create clips from the channel's videos and live streams.

This extends the list beyond comments and chat, so avoid entries that would unnecessarily prevent legitimate clip titles or descriptions.

Blocked Words Are Not a Policy Report

Holding or blocking a term on one channel does not report the user to YouTube or prove the message violates platform policy.

Use the separate Report action for spam, harassment, threats, or other Community Guidelines concerns that YouTube should review.

How to Build a Useful List

1. Start with recurring actual problems.
2. Prefer specific phrases over broad words.
3. Add common scam contact patterns.
4. Review false positives weekly at first.
5. Coordinate with managing moderators.
6. Remove outdated campaign-specific terms.
7. Test before important live streams.
8. Keep a private record of why each unusual term exists.

Common Blocked-Words Mistakes

• Assuming matching comments are permanently deleted.
• Using broad words that hold normal discussion.
• Expecting the list to apply to only one video.
• Ignoring live chat and Community effects.
• Approving users without understanding the bypass.
• Expecting retroactive removal of every old comment.
• Treating close matching as a perfect filter.
• Forgetting the impact on clip creation.
