You don't have to touch anything in the code, the event is using * to allow any sentence to trigger and then use $1- inside $hfind to find badwords, re-read my posts, the point is to pass the sentence of the user to $hfind, you don't specify "test" in the event, you add it to the hash table, this addition is eased by the usage of the /addbadword alias, which you have to call to add a badword.
I'd have told you if you needed to edit anything, instead I clearly said:
Just type /addbadword test test.
