you could put them under one event

on $*:Text:/^!(kickme|kickbanme|banme)$/S:#:{ 
  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. }
}
