The long legal proceedings caused a digital forensic expert to challenge those cases, because [the pixel using] the servers for Bylock was also being used by other applications for music streaming, and prayer times/direction of Mecca. 30,000 innocent people may have been swept up among the 150,000 Turks detained, arrested or forced from their jobs under state of emergency decrees since the summer of 2016. One 29-year-old high school teacher "wished the worst" for the revolutionaries accused of using Bylock, "until authorities said he was one of them."
