Code:
on *:text:*:#:{
  if ( $me !isop $chan ) { halt }
  if (%word.kick == on) {
    set %badword.line 1
    :badword
    if ( $read -l $+ %badword.line $mircdir\file_name == $null ) { halt }
    elseif ( $read -l $+ %badword.line $mircdir\file_name isin $1- ) { goto badwordkick }
    else { inc %badword.line | goto badword }
    :badwordkick
    if (%ban.bad.word == on) ban -u [ $+ [ %bad-word-ban ] ] $chan $nick
    kick # $nick kick message
    else { halt }
    :end
  }
}

maybe this is what you want? remember to change the lines

$mircdir\file_name that line in this code..

if you want it to ban, set %ban.bad.word on else set it off... to set the time for how long the ban should last, use set %bad-word-ban, set it to 60 would give a ban for 1 minute. to disable the script.. set %word.kick off ... and to enable it set it on..

if ($me != tired) { return } | else { echo -a Get a pot of coffee now $+($me,.) }
