Imagine a knock on the door after you have been on the Internet, blogging, and the next moment you are under arrest. Amnesty International launched a campaign in defence of Internet bloggers in many countries – including China, Tunisia and Iran who have been arrested for expressing views which have upset their governments.
But how have they been tracked down? It turns out that they have been turned in by major Internet providers such as Yahoo and Microsoft, who have supplied foreign governments with the information they need to pursue them.
