Why would you want to kick them too? If the word never comes up it is never said to anyone. Just stopping it should be enought. Kicking is a little extream for a word not really posted at all. What damage is a word never said? That would be like kicking everyone for thinking stuff. They come back and you tell them well I know you were thinking about cheating or saying tree so I kicked you...for example.
