Automatically moderate Twitch chat with message filters

You can fully adjust your built-in message filters to fit you and your community on Twitch.

Repeated messages filter​

The repeated messages filter removes messages which are the same or very similar to messages recently posted by the same person.

By removing repeated messages you are potentially able to drastically reduce the duration of your Twitch chat's Slow Mode, as the negative effects of doing so will be handled by the filter.

Being able to reduce Slow Mode means your viewers will be able to interact with you more often, and keep their conversations flowing without pausing to wait for their Slow Mode to expire.

Adjustable settings for the repeated messages filter​

Setting	Description	Default
Minimum characters in message before filtering	(⁎) Moobot will only check the message when its length is equal to or greater than this value.	70

Message expiration time (in minutes)	Moobot will only check the message against other messages which have been sent within this expiration time.	5

(⁎) Emotes do not count towards the filter's values.

(⁎⁎) Any emotes in the messages will be ignored when determining their similarity.

(⁎⁎⁎) By "repeated message" it means the first message must be found again. In other words, the 2nd message is the 'repeated message'. So if the value is set to «Allow a message to be repeated again once», it means the message will not be removed until the 3rd similar message is sent.

Special letters filter​

The special letters filter removes messages containing excessive use of special letters like «ⓔⓧⓐⓜⓟⓛⓔ».

Adjustable settings for the special letters filter​

Setting	Description	Default
Maximum special letters allowed in a message	Moobot will remove the message if it contains an amount of special letters greater than this value.	4

/me messages filter​

The nonexistent commands filter removes messages trying to use nonexistent bot commands.

Adjustable settings for the nonexistent commands filter​

Setting	Description	Default
Remove messages only after the second occurrence of a nonexistent command	Moobot will only remove the message if a recent message has used a nonexistent bot command.	ON

Fake removals filter​

The fake removals filter removes messages pretending to be deleted («message deleted by a moderator» variations.)

The Twitch bot can automatically announce in your Twitch chat when someone breaks your rules.

By announcing when and why someone is removed from your Twitch chat, you make everyone aware of your rules and the consequences for breaking them.

While in a filter's settings menu, use the toggle button for «Announcements» to toggle its announcement.

The announcement messages are also fully adjustable in the «Announcements» section of a filter's settings menu.

Once Moobot filters a user's chat message you have two options on how it will affect the chat message and user.

(⁎) If a user is put in a timeout they will be unable to send any more messages to Twitch chat until the timeout has expired. You can adjust the duration in the «Timeout duration» input, allowing you to adjust the severity of the repercussions.

Before giving a timeout, you can give misbehaving users a warning on their first offence. This allows them to learn your rules without any major repercussions.

To activate warnings for a filter, activate the toggle button for «Warning» while in a filter's settings menu.

Moobot gives a user one warning per filter.

Once a warning expires (usually after 24 hours), the user will be given another warning (instead of a timeout) if they get filtered again. You can adjust the expiration time in the «Warning expiration time» input once the «Show advanced options» checkbox is activated.

Having users acknowledge their offenses before they can chat again​

You can require users to acknowledge their offenses before they can chat again by activating the «The user must acknowledge the warning before they can chat again» checkbox in the «Warning» section of a filter's settings menu.

Moobot will display this acknowledgment message in the user's chat window, which they must click to continue chatting.

This allows your viewers to confirm exactly which of your chat rules they have broken, without any confusion or repercussions.

Moobot can perform this action for the user's first offense (warning) when you have set the warning to either «Don't remove the message nor the user» or «Remove only the message».

You can exclude certain special viewers from your auto moderation, like your Twitch subs, Twitch VIPs and Moobot regulars.

Activate any of the following checkboxes in the «Whitelist» section of your filter's settings menu to exclude these special viewers:

• «Exclude Moobot regulars (basic mode only)».
• «Exclude Twitch subscribers (basic mode only)».
• «Exclude Twitch VIPs (basic mode only)».

You can exclude certain special messages from your auto moderation, like Twitch re-sub alerts, highlighted messages from Twitch Channel Points, and chat messages with Bits.

Activate the various checkboxes in the «Whitelist» section of your filter's settings menu to exclude these special messages.

You can also adjust the amount of Bits required to exclude the chat message, by adjusting the «Minimum amount of Twitch Bits to exclude» value.

Your built-in message filters have two modes: «Basic mode» and «Advanced mode».

While your filters are in «Advanced mode», each user type can have their own unique filter settings applied to them.

This means that you can set up your filtering to e.g. make your fresh (new) Twitch subs have standard filtering applied to them, your normal non-subs have strict filtering, and your 5 year Twitch subs and VIPs have some very lenient filtering applied to them.

Follow these steps to activate «Advanced mode»:

1. Open up the «Moderation» menu from the main menu, then open the «Message filters» menu from there.
2. While in the «Message filters» menu activate the «Show advanced options» checkbox at the bottom of the menu.
3. Navigate to the «Advanced mode» section, which is now visible at the top of the «Message filters» menu.
4. Activate the toggle button in the «Advanced mode» section.
5. Click the «Enable» button in the confirmation dialog that pops up.
6. «Advanced mode» is now active, and you can set up the setting profiles for your filters.

You can set up unique settings for different users in Advanced mode by making a «Profile» for the type of user you want different settings for.

Adjusting the settings of a setting profile​

Follow these steps to adjust the settings of a setting profile:

1. Find the profile you want to adjust the settings for in the «Setting profiles» section of the filter's settings menu.
2. Click the pencil-iconed button (labeled as «Edit») in the profile's table row.
3. In the profile's settings menu, select the settings you want to adjust in the «Active settings» drop-down.
4. Adjust the settings to fit your needs.
5. (⁎) Repeat step 3 and 4 for each of the setting types («Lenient», «Standard», and «Strict»), and then in the «Active settings» drop-down select which setting type you want to be the active one.
6. Click the «Save» button at the bottom of the menu to save your changes.

(⁎) Step 5 is not required, but highly recommended so that you can easily switch between settings.

Different settings for a setting profile​

Each setting profile has 3 different setting types that you can switch between: «Lenient», «Standard», and «Strict».

Only one of them is active at a time, which you select in the «Active settings» drop-down.

This means if you want to make your settings more lenient or strict, you do not have to discard your previous settings, just switch to another setting type and adjust its settings, then switch back to your previous setting type at a later time.

By setting up and adjusting each of the different setting types for your profile, you can also temporarily override the settings, allowing you to switch your settings to e.g. be more strict when your Twitch chat becomes disorderly, or more lenient during a Twitch raid.

Excluding a setting profile from auto moderation​

You can exclude a setting profile from auto moderation by deactivating the «Enable message filtering» checkbox while adjusting its settings.

This means Moobot will deactivate the filtering for the selected filter for any user the profile applies to, allowing you to e.g. exclude your Twitch subs, Twitch VIPs and Moobot regulars from the filter.

Advanced mode allows you to override the active settings for all your filters, e.g. in case your Twitch chat becomes unusually disorderly.

In the «Select override settings» drop-down at the top of the «Message filters» menu, select which settings you want to apply, and give the duration of the override (in seconds.)

The active settings will then be (temporarily) switched over to your selection, being your «Lenient», «Standard», or «Strict» settings.

With Moobot's BetterTTV (BTTV) and FrankerFaceZ (FFZ) integration your message filters will correctly identify emotes from these extensions, and treat them as such instead of just ordinary words as vanilla Twitch chat sees them.

This allows your Moobot to apply the correct filtering for any messages containing such emotes, which avoids your viewers getting incorrectly filtered.

Follow these steps to activate the BTTV and/or FFZ integration for your Moobot:

1. Open up the «More» menu from the main menu, then open the «BTTV and FFZ» menu from there.
2. In the «BTTV and FFZ» menu find and activate the toggle buttons belonging to the integration you wish to activate.
3. Click the «Reload» button if you wish to immediately re-sync your emotes.
