So, if you should be interested in client/bot and join all 6 of their channels at the same time, and their poorly written on-join-whois script tags you 6 times, your client goes ahead and kills them?

I sure am glad you don't manage any large or public networks.

on *:SNOTICE:*did a /whois on you*: {
  ; Check if you are an IRCop.
  if (o !isincs $usermode) return
  ; The user's nickname and address.
  var %nick = $2
  var %address = $remove($3,$chr(40),$chr(41))
  ; Incriment variable +15, ticks down -1 every second.
  inc -z %WHOISKILL. [ $+ [ %address $+ . $+ $network ] ] 15
  ; If the variable exceeds 60, there were 5 sent in 1 minute.
  if (%WHOISKILL. [ $+ [ %address $+ . $+ $network ] ] > 60) {
    ; Kill the user.
    kill %nick Abusing WHOIS (Limit 5 /whois per 60 secs)
    ; Unset the counter variable.
    unset WHOISKILL. [ $+ [ %address $+ . $+ $network ] ]
  }
}

I'll let you figure out how to add /gline in there.
