Starting April, 2018 twitch users who receive 25 timeouts in a channel will be permanently timed out from typing in that channel’s chat and receive the following message:

“You have been permanently timed out from this channel. Refer to the Twitch terms of service for additional information.”

Broadcasters and channel moderators appointed by the broadcaster are equipped with a set of commands and features that will allow them to closely monitor and moderate the chat. These features and commands range from giving a user a quick timeout to built in anti-spam.

To use any command or chat feature simply type the required command into the text-box and hit enter.
Please note that words surrounded by the “less than” (<) and “greater than” (>) symbols indicate a required value, for example: <username> would require a username (i.e. “Justin”).
A word surrounded by square brackets ([ and ]) indicate an optional value, for example: [seconds] could optionally be left out, or replaced by a number of seconds (i.e. 10).
The symbols themselves ([, ], <, and >) are not to be included into the text box when entering your command.

Timeout
This command allows you to temporarily ban someone from the chat room for 10 minutes by default. This will be indicated to yourself and the temporarily banned subject in chat on a successful temporary ban. A new timeout command will overwrite an old one.
The command also supports banning for a specific set of time via the optional [seconds] value.
To clear a timeout, either use the Unban command or overwrite the current timeout with a new, 1-second one.
Usage: /timeout <username> [seconds], or clicking the clock symbol either directly in chat or on the user badge which appears when clicking on a username.

Ban
This command will allow you to permanently ban a user from the chat room.
Usage: /ban <username>, or by clicking the Cancel symbol either directly in chat or on the user badge which appears when clicking on a username.

Unban
This command will allow you to lift a permanent ban on a user from the chat room. You can also use this command to end a ban early; this also applies to timeouts.
Usage: /unban <username>, or by clicking the Unban button which replaces the Ban button.

Slow
This command allows you to set a limit on how often users in the chat room are allowed to send messages (rate limiting).
Usage: /slow <seconds>
Note: Twitch Partners with a Subscription Button can allow their Subscribers to bypass the slow mode filter if they so wish to do so by going to their dashboard and navigating to their subscriptions tab.

Slowoff
This command allows you to disable slow mode if you had previously set it.
Usage: /slowoff
