Twitter: 5K tweets removed this year over copyright complaints

Twitter released its first ever Transparency Report detailing statistics on international requests for user data and content removal today, the same day news came out that it would have to hand over user information in a court case in New York.
The Twitter Transparency Report breaks down the countries from where such requests come and specifies how many requests it has received, what percentage it complied with, and numbers of user accounts affected, all spanning the first six months of this year.
The company has received more government requests in the first half of this year than in all of 2011, Jeremy Kessel, manager of legal policy at Twitter, wrote in a blog post. The company notifies affected users of requests for their account information unless it is prohibited from doing so by law.
In the U.S., Twitter fielded 679 requests for user information from Twitter, involving 948 accounts. There were 98 requests in Japan for information from 147 accounts, and Canada and the UK both had 11 requests, with the other countries listed as having fewer than 10. Twitter provided the information requested in 63 percent of the cases overall, but did not specify how many of the cases were made by governments seeking user data in connection with criminal investigations.
One of those cases involved a man arrested for disorderly conduct during an Occupy Wall Street protest on the Brooklyn Bridge last October. Twitter had challenged a subpoena seeking three months of user account information and tweets from the defendant's Twitter account, but a criminal court judge in New York this weekend ordered the social network to hand over the data.
