Keywords..... The GCHQ Rumour

There is a rumour that every email we send and every web page written is scanned by massive computers deep inside GCHQ or Langley or wherever such things are done these days.
If certain "Key words" are present then our further activities are subject to scrutiny by the grey people who sit in dark room and never see the light, reading page after page of email and web blog on the off chance that we may be planning to smuggle 200cc of water on the the next flight to Glasgow.
The fun thing to do would be for everyone to have an email signature containing as many keywords as they can using white text on a white background, thereby not annoying the email recipients but having a great time with the government mail scanners.
Here are a few to be getting on with (scandal, immigrant,Terrorist, gun, assassinate, blow up, kill, 9/11, Bush, Blair, Nuclear bomb, Washington, Dirty Bomb, Smuggle, Drugs, take over. revolution, attacks ), no really they are there.
The theory also goes that if you put these key words into you emails and blogs then more people will know about you when they search on these words.
I shall just have to wait and see if that one is true.
