Answer 1

you know what as long as i have been using my internet i have never seen these words used -Ever, even in racial or anti government outburst! have you??

And this is probably how they would know because they are not words used by the common fellow on chat email or anywhere else,
and they I am sure have all records of all you, I and every one ever say to one another at all times.
its the words that gives them a red flag.
