A simple yet powerful ban protection script I've made. Look in the nicklist for the add/delete commands. Also, if the person has ban protection enabled it will counter it. Also unbans you using chanserv.

on *:ban:#:{
  if (%protect. [ $+ [ $banmask ] ] == $null) { halt }
  mode $chan +e $banmask
  if ($nick != $me) { 
    kick $chan $nick Nice try, $nick $+ .
    mode $chan +b $address($nick,2)
  }
  mode $chan -b $banmask
  msg $chan -3Protection engaged- $banmask was unbanned -NeOiRc v2.0-
}

on *:rawmode:#:{
  if (-e isin $1-) {
    if (%protect. [ $+ [ $2 ] ] != $null) {
      mode $chan +e $2
    }
  }
}

on *:join:#:{
  if (%protect. [ $+ [ $address($nick,2) ] ]) {
    mode $chan +e $address($nick,2)
  }
}

on *:kick:#:{
  set %kchan $chan
  if ($knick == $me) {
    /cs unban %kchan
  }
}
