InspIRCd v4 is still early in development!

If you use this branch you may experience crashes, weird behaviour, and unannounced breaking changes.

You probably want to use InspIRCd v3 instead.

The "messageflood" Module (v4)

Description

This module adds channel mode f (flood) which helps protect against spammers which mass-message channels.

Configuration

To load this module use the following <module> tag:

<module name="messageflood">

<messageflood>

The <messageflood> tag defines settings about how the messageflood module should behave. This tag can only be defined once.

Name Type Default Value Description
kickmessage String Message flood (trigger is %lines% messages in %duration%) The message to use when kicking users that hit the message flood trigger.
notice Decimal 1.0 The number of lines that a single NOTICE message is equivalent to.
privmsg Decimal 1.0 The number of lines that a single PRIVMSG message is equivalent to.
tagmsg Decimal 0.2 The number of lines that a single NOTICE message is equivalent to. This should be lower than the other commands to avoid users being kicked by automated client features such as typing notifications.

The kickmessage field can contain any of the following template variables:

Variable Description
%duration% The seconds from the mode value as a duration.
%lines% The lines from the mode value.
%seconds% The seconds from the mode value.
Example Usage
<messageflood kickmessage="Message flood (trigger is %lines% messages in %duration%)"
              notice="1.0"
              privmsg="1.0"
              tagmsg="0.2">

Channel Modes

Name Character Type Parameter Syntax Usable By Description

Exemptions

Name Description
flood Allows exempted users to send messages at a higher rate than channel mode f (flood) allows.
