Before live chat messages are held for review, you have to enable the feature for your channel.

Disable "hold for review"

2. Go to youtube.com/comment_management.
3. Under "Messages" in your Live Chat, untick the checkbox for "hold potentially inappropriate chat messages for review."

You can assign moderators for all live chat sessions. Moderators remain on the list until they are unassigned.

We strongly recommend that you have at least one dedicated live chat moderator for high-traffic events. Moderators can interact with the audience and remove comments when appropriate. They can also flag, hide, or put users in time out.

Assign moderators

Select menu next to username in chat and select Set User as Moderator or follow these instructions:

1. Click the three dots (...) next to the chat text box.
2. Enter a username.
3. Set up one list of moderators for your channel. Moderators remain on the list until they are unassigned.

Inline moderation

On desktop, hold down 'ALT' / 'Option' on your keyboard to pause the chat feed and hover over messages. You will see options to delete the message, place the user in time out, and hide the user from the chat message feed or comments section on your channel.

Manage spam messages

Select the checkbox for Automatically block spam messages checkbox. This blocks simple spam such as long messages in all caps or repeated identical messages by the same user.

Block words proactively

• Compile blocked words in the Community Settings section. Live chats matching these words will be blocked.
• You can also block links from being used in comments by typing "*links*" into the Blocked words field.

Hide a viewer from live chat

Select menu next to the chat message and select Hide User or follow these instructions:

1. Go to the viewer's YouTube channel.
2. Click the About tab.
3. Click on the flag and select Hide.

Note: This will also hide the user from the comments. Users you have hidden will be visible in Hidden Users in Community Settings.

Unhide a viewer from live chat

To remove hide status:

1. Go to the viewer's YouTube channel.
2. Click the About tab.
3. Click on the flag and select Unhide.

Note: Once a user's hide status has been removed, they will once again be able to leave comments and live chat messages on your channel.

1. Type “@”.
2. Begin typing their username.
3. Select the username. 
    

The chatter will see their username highlighted in orange, which is visible only to the chatter whom you’ve mentioned. This makes it easier for them to see your response in the chat feed. 

During a live stream, you can embed live chat on your own side by using an iframe.

1. Get the video ID for the live stream. You can get the video ID from the watch page URL (youtube.com/watch?v=12345). In this case, the video ID is ‘12345’.
   • If you chose "Stream now," right-click on the player and select Copy video URL to get the video URL.
2. Get the domain URL for the site you want to embed chat on. If you're embedding chat on www.example.com/youtube_chat, your embedding domain is "www.example.com."
3. Combine the embedded URL in the following way: https://www.youtube.com/live_chat?v=12345&embed_domain=www.example.com.
4. This is the URL for your iframe. Note the embed_domain must match the the URL of the page you’re embedding the chat on. If they are different, the embedded chat will not load.

1. Go to History.
2. At the top of the page, click Live chat.
3. Go to the post you are looking to delete (Chats are in reverse chronological order.)
