Rocked by domestic and international unrest as well as an increasingly authoritarian government, Turkey's government has in recent years frequently turned to mass censorship as an answer to unsolved political problems.
Social networks like Facebook and Twitter have become regular targets of Turkish censorship, especially when the country's citizens criticize government leaders and institutions.
Twitter, like its Silicon Valley competitors, complies with government censorship demands but says that it attempts transparency by reporting every blocked tweet that it legally can. This new research casts doubt on the trustworthiness of any of these reports.
“Our work establishes that Twitter radically under-reports censored tweets in Turkey, raising the possibility that similar trends hold for censored tweets from other countries as well,” the researchers wrote.
Twitter's reports understate the censorship by two orders of magnitude. The true number of censored tweets reaches over 250,000 ACM found.
The new statistics provoked pointed criticism of Jack Dorsey, Twitter's CEO.Twitter didn't respond to a request for comment.
