Twitter is following Google’s lead in publishing more details about takedown requests sent by governments and rightsholders over tweets on its network. There’s a new site – transparency.twitter.com – and a report on requests from Q3 and Q4. “It is vital for us (and other Internet services) to be transparent about government requests for user information and government requests to withhold content from the Internet,” blogs the company. “These growing inquiries can have a serious chilling effect on free expression – and real privacy implications.” Anti-piracy outfit Websherriff filed the most copyright takedown notices in the second half of 2012 – but with only 199 sent. The RIAA was the third-keenest takedown sender with 120. Small beans compared to the blizzard of DMCA notices going to Google, of course.
