so you have the bot or what ever you are running this script to say the word that you just banned the person for saying , and you also warn them right before you kick ban them kind of pointless...
why not just do this and be done with it?

on @*:text:*:#:{
  var %curse = add,ur,curse,words,here, %x = $numtok(%curse,44)
  while (%x) {
    if ($istok($1-,$gettok(%curse,%x,44),32)) ban -ku86400 # $nick 2 Banned For 24 hours
    dec %x
  }
}
