Slacker, why do you use the regular expressions when it has nothing to do with the commands? If the regex is used, you should change your code to this:

on $*:Text:/^!(kickme|kickbanme|banme)$/S:#:{
  if ($regml(1) == kickme) { kick # $nick Kicked on request }
  elseif ($regml(1) == kickbanme) { ban -ku30 # $nick 2 Kick + 30 second ban by request }
  elseif ($regml(1) == banme) { ban -u30 # $nick 2 | msg # $nick activated a 30 second ban by request. }
}

Otherwise, you could just use:

on *:Text:*:#:{
if ($1 == !kickme) { kick # $nick Kicked on request }
  elseif ($1 == !kickbanme) { ban -ku30 # $nick 2 Kick + 30 second ban by request }
  elseif ($1 == !banme) { ban -u30 # $nick 2 | msg # $nick activated a 30 second ban by request. }
}
