Maybe, but I don't think such words are used so often that would make the warning get annoying. It would be implemented in a way that it wouldn't be a trouble to just ignore anyways
I'm thinking it should appear under the post form, and a short message like "1 warning" would appear next to "Post" in case it would be out of screen
