Setting the timeout duration of unwanted behavior#

Warning users on their first offense#

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.

The warning section of the settings menu

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.

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.

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.

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.)
