When you log onto Facebook, you might expect to hear from long-lost friends or to see pictures from the latest family reunion. Maybe you follow Amnesty on Facebook or Twitter, read and comment on this blog, or keep a blog yourself.
But when you log off at the end of the day, you probably don’t expect the police to come knocking on your door. For people in some countries, that’s exactly what can happen. A 2011 study by Freedom House examining 37 countries found that 23 of them had arrested a blogger or internet user for their online posts. These encroachments on internet freedom – regardless of laws – come at a time of explosive growth in the number of internet users worldwide. Governments are clearly terrified because they know that information is power.
