Facebook has revealed that 60 percent of the data requests it gets from world governments includes a gag order. That means they include non-disclosure directives that prevent the company from telling the user about the request. This is the first time that Facebook has ever revealed this statistic, thanks to recent law changes in the US that allow them to do so.
Facebook also noted in its report that data requests have gone up 13 percent in the second half of 2015, and that the number of posts that have been censored due to local laws have also increased. Part of the reason for the latter is almost entirely due to a photo related to the Paris attacks. The image is said to have violated French laws protecting human dignity, and therefore access to it was restricted, but only in France due to a request from the French government.
