myLot Rules about permitted words

Tweet

I am very new to myLot and excuse myself in advance if there is anything I got wrong. What do you think about this: Responding to a political commentary I didn't like, I happened to mention some names: George (talking about George Bush), Karl (talking about Karl Rove) and, why not, the first name of Vicepresident Chaney. Then I pressed submit. Next I stared at a message telling me that the first name of Vicepresident Chaney is not a permitted word. That's why I avoid to write it in this place. I once heard that a word that sounds like the first name of Vicepresident Chaney, must not be used in conversation, but I never would have thought of it in this context! Shouldn't myLot use a more context conscious software in order to filter out unwanted vocabulary? Or is this impossible?
