Kicks specified user off a given channel. Only channel operators
are privileged to use this command. Channel operator privileges
can be given to other users of channel using:
mode <channel> +o
kick can be very effective if used in a combination with
mode #channel +i
and possibly
mode #channel +b.
First line of defense should be ignore and kick then then the
channel can be made invite only, and if all else fails a person
can be banned from the channel.
The <comment> is to supply some reason for the kick to the user
affected as well as to other people on your channel.
IMPORTANT NOTE:
Be careful with your use of KICK and MODE #channel -o
as they can throw the network permanently out of sync. This
generally occurs when two people are bickering about channel op
status and de-op each other. This generates 'Fake MODE' notices
which are an indication that something is wrong. The best way
to avoid this is to not use ON and MODE together.
