For the module to be functional, you also have to go to Site Manager -> Settings -> Bad words and check the Check Bad Words check-box.

 

You can also set the default action that will be taken in case that a bad word is detected and the word has no action defined. This is done using the Bad word action drop-down list. Using the Bad word replacement property, you can define the default replacement text that will be used in case that a bad word is detected, has the Replace action set and has no replacement text defined.
