Users that are not connected to your Peertube instance are joining the chat using "anonymous accounts" (they can freely choose a nickname, and will be assigned a random avatar).
This mode can be usefull for example: <ul> <li>To avoid spam or offensive message when you are not here to moderate.</li> <li>When there are too many speaking participants, and you can't no more moderate correctly.</li> </ul>
You can enable some external authentication methods to allow user to create chat accounts.In such case their nickname and avatar will be automatically initialized with the remote account information.
To enable or disable this mode, you can use the room configuration form. If you want to enable it for all your chatrooms at once, you can use the button bellow.
This also allows user to join the chat without creating Peertube account (in case your instance has closed registration for example, or without waiting for account approval).

By enabling this option, the moderation bot will automatically delete messages containing more than X special characters. Special characters are those that don't fit into one of these categories: letters, numbers, punctuation symbols, currency symbols, emojis.

By enabling this options, the moderation bot will automatically moderate duplicate messages. That means if a user send the same message twice within X seconds, the second message will be deleted.
