Add Substring Support
At the moment it is easy to include profane words - I can for example include f##kface and it is not picked up as profane. Maybe add the ability to look for specific substrings?
What might help your requirement is using the "classify = true" parameter with the API to enable machine-learning based text classification feature on the text, in addition to the term-based profanity filtering.
For example, if I used your example word in a sentence as in "You f##kface!", or just "f##kface!" you will see a high offensive score ("Category 3") and the ReviewRecommended flag is set to True.
Hope this helps.
