Brothel clients’ data: The app has reportedly allowed approximately 6,400 sex work establishments to share private customer data, including 4.6 million phone numbers, past records of visiting other brothels, occupations and even sexual preferences. Local authorities have taken three of the offenders, including the app developer, into custody for questioning, while the other 12 individuals were booked without physical detention. The suspects will be facing charges for violating the law on personal information protection and the law on punishment of prostitution.
