You can define in which cultures will a certain bad word be filtered. If you choose to Edit () a bad word in the list in Site Manager -> Administration -> Bad words and switch to its Cultures tab (the tab is not available in the New bad word dialog), you will be offered with the following two options:
|•||The word is not allowed in all cultures - the bad word will be filtered in all website cultures|
|•||The word is not allowed only in following cultures - the bad word will be filtered only in cultures added to the list below|
Using the Add cultures button, you can add cultures to the list. The Remove selected button removes all cultures selected by the check-boxes from the list.
