Announcing unwanted behavior in Twitch chat

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.

Tip: If you want to disable the announcements, you can disable all auto moderation announcements in the «General settings» menu instead of disabling them for each individual filter.

Setting the timeout duration of unwanted behavior

Once Moobot filters a user's chat message, it removes their message from chat, and then puts the user in a chat timeout where they cannot send any more messages to Twitch chat until their timeout has expired.

You can adjust the duration of the timeout in the «Timeout duration» input, allowing you to adjust the severity of the filter's punishment.

Warning users on their first offense

By giving misbehaving users a warning on their first offence you allow them to learn your rules, but without you coming down on them full force.

A warning lasts 24 hours, and Moobot gives a user one warning per filter.

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

You have several options on how warnings affect the chat message and user:

1. Don't remove the message nor the user:

The chat message and user will be unaffected, but Moobot will make an announcement in Twitch chat (if activated.)

2. Remove only the message:

Moobot will remove the single offending chat message, but the user and their past and future messages will be unaffected.

3. Remove both the message and the user:

Moobot will remove the offending chat message, and the user's recent messages. Moobot will also put the user in a temporary timeout.

You can adjust the duration of the warning timeout separately in the «Warning timeout duration» input.

Excluding special Twitch viewers from auto moderation

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)».

Note: These options are only active while your filtering is in Basic mode. You can accomplish the same in Advanced mode by assigning a Profile to your Twitch subs, VIPs and Moobot regulars, and adjusting that profile.

Excluding special Twitch chat messages from auto moderation

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

Activate the «Exclude Twitch subscription announcements» and/or «Exclude messages containing Twitch Bits» 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.

Basic mode vs. Advanced mode

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.

Mode	Pros	Cons
Basic mode	No need for adjustments.	Cannot have different settings for certain users, only toggle off/on for Twitch subs, VIPs and Moobot regulars.
Advanced mode	Can adjust the settings for each user type, allowing more strict or lenient settings for certain users.	Requires additional adjustments.

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 «Enable advanced mode» checkbox.
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.

Note: You can go back to «Basic mode» by deactivating the «Advanced mode» checkbox at the top of the «Message filters» menu.

Using different settings for different users

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 your setting profiles

Follow these steps to adjust your setting profiles:

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, make sure you have activated «Advanced mode», and then click the «Settings» button for the filter you want to adjust the setting profiles for.
3. While in the settings menu, at the bottom of the menu, click the «Edit» button to the right-hand side of the «Setting profiles (Advanced mode)» section.
4. Make different profiles for each user type you want to have different settings for, by clicking the «Add a profile» button at the bottom of the menu.
5. Adjust the sliders of the profiles to only show the user type you want each profile to apply to. You may have to adjust your Tiers if you do not already see the specific user type you want.
6. Make sure you have a profile set for every one of your Tiers, which will make the menu green (opposed to red) with an «All good!» message displayed at the top of the menu.
7. Click the «Save» button at the bottom of the menu.

Now adjust the settings of each of the setting profiles you created.

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 the spam filter for this specific group and settings» 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.

Note: The exclusion setting is tied to the different setting types of the profile: «Lenient», «Standard», and «Strict», which makes it possible to deactivate the filter for the profile's «Lenient» settings, while keeping the filter active for its «Strict» settings.

Easily switching between lenient and strict filtering

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.

Note: To properly take advantage of this functionality, make sure your «Lenient», «Standard», and «Strict» settings are properly and individually adjusted for each profile of each of your filters.
