TheProdigY, I'll recommend this:

on @*:TEXT:*:#:$cuss($1-)
on @*:ACTION:*:#:$cuss($1-)
on @*:NOTICE:*:#:$cuss($1-)
alias -l cuss {
  tokenize 32 $strip($1-)
  var %cuss = 1, %swear = $me @#$ black nigga negro niggah n1gger kike !@#$ !@#$ !@#$ SyracuseChat
  while ($gettok(%swear,%cuss,32)) {
    if ($findtok($1-,$v1,1,32)) {
      kick $chan $nick Please don't use that kind of language here.
    }
    inc %cuss
  }
}

This way you cover the text, action and notice event together.
