Thai police arrested three Chinese people who used several computers to control 500 fourth and fifth generation iPhone smartphones. Law enforcement officers who found 350 thousand unregistered SIM cards at the crime scene found out that the technique was used not in an illegal call center, but in fan mailing to users of the WeChat messenger, which was popular in Southeast Asia. Besides the illegal workers artificially increased the popularity of applications, sold online through the same WeChat. Each of them received about $ 4,000 in monthly equivalent for their activities. Since the legislative framework for violating business rules on the network has not yet been well regulated, bot farm employees have been charged with working without official permission, smuggling and using unregistered SIM cards anywhere. Details of the investigation have not been disclosed.
