Simple workaround (since this is basically what these events are for):
on *:NOTIFY: if $istok(ParaBrat Hammer landonsandor,$nick,32) { echo -atic notify * $nick ison IRC }
on *:UNOTIFY: if $istok(ParaBrat Hammer landonsandor,$nick,32) { echo -atic notify * $nick has left IRC }
or set the nicks you want into a %variable and use $istok on it.
/set %SpeshulNicks ParaBrat Hammer landonsandor
on *:NOTIFY: if $istok(%SpeshulNicks, $nick, 32) { echo -atic notify * $nick ison IRC }
