Government requests for information on Twitter users rose 40 percent in the past six months, according to the firm's latest six-month transparency report.
In total 2,871 requests for account information were filed in the second half of 2014, compared with 2,058 in the first six months. These requests contained demands for information on a total of 7,144 Twitter accounts.
The US and Turkey filed the most requests. The US filed 1,622 relating to 3,299 accounts, which Twitter complied with 80 percent of the time.
Turkey filed 356 requests relating to 496 accounts, but Twitter did not comply with any. Russia, meanwhile, filed 108 requests and again Twitter did not comply with any.
This was the first time Russia has filed any such requests, showing that the authorities are monitoring social sites more closely, possibly owing to the tense situation in Ukraine.
The UK filed more requests than Russia, though, at 116 relating to 371 accounts. Twitter complied with 34 percent of these notices.
Account removal data
Meanwhile, requests for content removal increased by 84 percent, from 433 between January and June 2014, to 796 between July and December 2014.
The majority of these requests were received from Turkey, which filed 477 notices. Twitter complied with half of these, despite attempts to challenge the notices in court.
"We received 328 court orders and 149 requests from Turkish government agencies directing Twitter to remove content ranging from violations of personal rights to defamation of private citizens and/or government officials," Twitter said.
The US, by contrast, filed just 32 such requests, with zero compliance from Twitter.
In the UK authorities requested 22 accounts be taken down, but again Twitter did not comply with any.
Russia filed 91 requests, of which Twitter complied with 13 percent. Jeremy Kessel, senior manager for global legal policy at Twitter, said that the firm rejected many notices for those using Twitter not to discuss the situation in Ukraine.
“We denied several requests to silence popular critics of the Russian government and other demands to limit speech about non-violent demonstrations in Ukraine,” he said.
Twitter is just one of many tech companies to release data on information requests from governments as the industry aims to provide transparency on the actions of authorities around the world.
