Google's semi-annual Transparency Report features detailed analysis and statistics for government takedown requests, broken down by nation. From this, I learned that Brazil's government sends more Google takedowns than anywhere else, thanks to the combination of a national election and the popularity of Orkut, Google's social networking service.
India's government generates the largest number of bogus takedowns. 88 percent of Indian government takedown requests to Google are denied: "We received requests from different law enforcement agencies to remove a blog and YouTube videos that were critical of Chief Ministers and senior officials of different states. We did not comply with these requests."
Meanwhile, the UK leads the world in the volume of materials taken down: 93,518 removals in 2010, "The UK's Office of Fair Trading requested the removal of fraudulent ads that linked to scams. We complied with the request and removed 93,360 items in total."
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
