Actually, considering that VTNC is posting that string in a public area, what's the point? I mean, it's one thing to use it in email, to protest and hinder how the Government might be reading private communication, it's another when you are just posting it in the open.
Is VTNC against the US reading public posting? Where's the privacy concern in such a case? Why shouldn't the US Government know about people using "hot" words in the public arena?
