Link Filter in YouTube Live

How the Link Filter Works in YouTube Live

The link filter prevents messages containing URLs from appearing in the public stream chat right away. Such messages are sent for review. Depending on your settings and the YouTube interface, you can approve them, delete them, or leave them unpublished.

This is useful against promotional spam, suspicious offers, phishing pages, and messages from bots. However, the filter does not remove links from all sections of your channel. It applies to live stream messages, not to the video description, the "About" section, external panels, or other places where you post information.

This setting works separately from the automatic review of potentially inappropriate messages. The link filter looks specifically for URLs and similar addresses, while the automatic moderation system evaluates message content based on other criteria. You can use both tools at the same time to protect your chat.

Item names may vary slightly depending on the interface language and YouTube Studio updates. Typically, the relevant setting is called "Block links" and is located in the community automated filters section.

How to Enable Link Blocking in YouTube Studio

The most reliable way to change this setting is in the browser version of YouTube Studio on a computer. In the YouTube Studio mobile app, the relevant section may be missing or located somewhere other than in the full version of the site.

1. Open YouTube Studio and select the desired channel. If you have multiple channels or brand accounts, check the name and avatar at the top of the page.
2. In the left menu, click "Settings." The button is usually located at the bottom of the sidebar.
3. Go to the "Community" section. In some interface versions, it may be called "Community moderation."
4. Find the "Automated filters" block. It will contain a "Block links" item or a setting with a similar description: messages containing URLs are sent for review.
5. Check the box next to this setting and click "Save."

After saving, the filter begins applying to new chat messages. As a rule, it does not review already published messages retroactively, so you will have to delete old spam separately.

If the item is missing, first refresh the page and check that you opened Studio and not regular YouTube. Another possible reason is insufficient channel access level. In that case, the settings must be changed by the owner or a user with appropriate permissions.

How to Verify the Filter Is Working

It is best to test the setting before an important stream. Do not use your main public chat for this: a test message with an address may be seen by your audience if the parameter was not saved or was enabled on the wrong channel.

Create a test stream with restricted access if your channel has that option, and send a message with a regular URL from another account. You can also ask a trusted moderator to check the chat. Do not follow the address from the test message and do not open unknown pages.

With the setting correctly enabled, the message with the link should not appear immediately among regular messages for viewers. It may end up in the review queue in the stream management window. The exact location of this queue depends on the current YouTube interface.

Test several formatting variations:

• an address starting with https://;
• a domain with the www prefix;
• a link with a period at the end of the sentence;
• a message where the URL is next to regular text.

After testing, delete the test stream or leave it inaccessible to viewers. If the message still appears immediately, reopen your channel settings, make sure the box is checked, and save the changes again.

What Happens to Messages Containing Links

An enabled filter does not mean that every message with a link will be permanently deleted. Its purpose is to prevent automatic publication before review. This is important to keep in mind if viewers share useful materials, schedule links, tournament results, or additional sources.

During the stream, check the message queue in the stream management room. A safe message can be approved, while a promotional or suspicious message can be deleted. If one user regularly sends spam, apply separate moderation measures to them: deleting messages, temporary restrictions, or hiding the user from the channel.

Do not approve a URL just because a familiar name is written next to it or a reward is promised. Check the domain and the meaning of the message. Phishing links are often disguised as a giveaway, a vote, support for the creator, or an urgent notification about account suspension.

Also consider the downside of the filter: it may delay useful links from regular viewers. If your audience frequently needs to receive materials, place official addresses in the stream description or in another pre-prepared section. Leave only those links in the chat that you are genuinely ready to review manually.

Why Some Links May Bypass the Filter

The filter does not replace ongoing moderation and does not guarantee that no promotional message will appear in the chat. Users can distort addresses: add spaces, replace the period with words, use images, characters from other alphabets, or send only the site name without a full URL.

The automated system may also handle shortened addresses, non-standard domain zones, and text that merely resembles a link differently. Therefore, a suspicious message without an obvious URL should not be approved automatically either.

If spam keeps recurring, supplement the filter with other tools:

• add frequently occurring words, names of advertised sites, or phrases to the blocked words list;
• assign trusted moderators for the duration of the stream;
• enable slow mode to limit message frequency;
• use subscribers-only chat mode if it suits your audience;
• delete repetitive messages and hide accounts that systematically break the rules.

Do not add overly general expressions to the blocked words list. Otherwise, the filter may hold back regular viewer messages and complicate communication during the stream.

What the Link Filter Does Not Block

The setting does not remove URLs placed in the stream description, channel description, social media profiles, or on external pages. It is also not a full-fledged fraud protection and does not verify the safety of each domain.

If you are streaming with multiple moderators, agree in advance on which messages to approve and which to delete. You can briefly state the rules in the stream description: for example, ask viewers not to send promotional links and not to follow addresses from unfamiliar users.

Pay separate attention to links sent by the host or a moderator. Before publishing, check the address so viewers do not get an erroneous or outdated page. For official resources, it is better to use one clear set of addresses and not change it during the stream unless necessary.

If the chat remains flooded with advertising after enabling the setting, the problem may not be only about URLs. Use manual moderation, message rate limiting, and blocking of repetitive phrases. These measures complement the filter, but none of them eliminates the need for oversight during an active stream.

Quick Summary: What to Do Step by Step

1. Open YouTube Studio in a browser and select the desired channel.
2. Go to "Settings" → "Community" → "Automated filters."
3. Enable the "Block links" item and save your changes.
4. Test the setting on a test stream or with the help of a trusted moderator.
5. Before the stream, prepare manual moderation and, if necessary, enable slow mode and subscribers-only chat mode.
