Channel Blocked and Permitted Terms, Powered by AutoMod

Twitch’s Blocked Terms filter helps to protect you and your viewers. Permitted Terms helps decrease your mods’ workload by automatically permitting terms that AutoMod catches but you allow.

Note: There are some terms and malicious URLs that Twitch blocks automatically.

Utilizing these features can help streamers to:


 * 1) Protect their personal information.
 * 2) Protect against spambots.
 * 3) Reduce toxicity in chat in conjunction with other common settings, AutoMod, chat bots and chat rules.
 * 4) Reduce mod workload by automatically blocking or permitting terms that AutoMod catches but you always deny or allow.

Blocked Terms
In your channel settings you will find a section for "Blocked/Permitted List, Powered by AutoMod":

To use this feature, type the word you wish to have blocked from your channel, submit it, and scroll to the bottom of the Channel Settings page to save your changes. Your Blocked Terms list will work with all AutoMod settings, including Level 0.

You may add terms containing multiple words. Messages that contain all words in the term will be blocked, without blocking messages that contain only one word in the term (e.g. adding “hi there” as a term will not block messages containing only “hi” or “there” but will block messages containing “hi there” or “there hi”). The number of terms you can filter is in the tens of thousands, so you do not need to worry about reaching the cap. Messages containing channel-blocked terms will not be posted to your chat.

You will notice that there are some asterisks on the beginning and ends of words in the example. Those are wildcards, which will match zero or more characters at the start or end. For example, we have "hate*" as a banned word. So if anyone typed "haters" or "hateful" those messages would be blocked. You can also use this feature to filter any variant of a url. *someurl.com*` for instance would filter " http://someurl.com ", " http://someurl.com/somepage ", " http://www.someurl.com/some/other/page?abcdef ", etc. This can protect your chat from variations of links that are unwelcome.

You will also notice that one term in the above screenshot, “naughty,” is temporarily blocked by your mods. If you are using AutoMod, some messages will be held for mods to allow or deny. If they deny the message, the term that caused the message to be caught will automatically be blocked for a limited time. As mods deny future messages containing the same term, the duration of the temporary automatic block extends: from one hour, to one day, to seven days, to permanent. At any point, you may remove a term from the list of temporarily blocked terms, or add it to the permanent list.

Permitted Terms
Below the Blocked Terms list, you will find the Permitted Terms list. Adding terms to your Permitted Terms list will prevent AutoMod from catching messages containing those terms (as long as those message do not contain other terms caught by AutoMod or that appear on your Blocked Terms list). This list will help reduce your mods’ workload by automatically allowing message containing terms that AutoMod catches but you permit in your chat.

When your mods choose to allow a message, it will be added temporarily to your Permitted Terms list, in the same way that denying a message will temporarily add it to your Blocked Terms list. As mods allow future messages containing the same term, the duration of the temporary automatic permission extends: from one hour, to one day, to seven days, to permanent. At any point, you may remove a term from the list of temporarily permitted terms, or add it to the permanent list.
