ISTANBUL – Turkey filed over five times more content removal requests to Twitter than any other country in the second half of 2014, data published by the micro-blogging site showed on Monday. The figures are likely to reinforce fears of a crackdown on Internet freedom in the predominantly Muslim NATO state where President Tayyip Erdogan has said he is determined to stamp out what he sees as illegal online activities. Twitter’s transparency report showed Turkey filed 477 content removal requests between July and December, an increase of more than 150 percent compared to the first six months of 2014. Russia and Germany followed with 91 and 43 removal requests respectively. Overall, government requests for removal of material were up by 40 percent.
