What is this 1999, when 99% of the people seem to be computer illiterate? On her facebook wall she posts his email and letter in full!? Well, seems we are at the point of frictionless sharing, let the hacking begin people - nothing is secret, no respect for anyones privacy!
And no, I don't think human rights activists goal should be to cause the most trouble.
