It is somtimes assumed that this command is nothing more than a short way of typing  /mode #channel +b. This tutorial aims to correct that misconception.
 

Intent

The BAN command is used for maintaining a record of bans on the bot for it to act upon when neccessary. How the bot reacts to the command depends on the situation. Sometimes it may ban the host and kick out any users who match the banmask, while other times it may simply report it has stored the ban, and take action at a later time.
 

Usage

The ban command has several arguments which may be used, but only one is mandatory. The usage of the command is as follows:

                   botnick ban victim bantime reason
or      /msg botnick ban #channel victim bantime reason

The last two fields are optional, and function independantly of each other. You may specify a bantime without neccessarily specifying a ban reason, or specify a reason leaving the bantime redundant.
