People do know you can sign up to get a feed of *every* public tweet, don't they? http://gnip.com/products/realtime/firehose/. Samaritans could have signed up to that and monitored the entire (Twitter) world and no-one would be any the wiser.
Apparently not just Twitter either. FourSquare (location) is on there too, and WordPress (blogs) and Disqus (comments).
