Many operators are falling under blame for incidents in which money has been swindled out of their regular customers when big data collected from users' daily life was utilized against them, Science and Technology Daily reported.
A customer recently shared his experience online that he used to book hotel on a travel website for the price of 380 yuan (about $60) per room. However, he inadvertently discovered that the marked price for such a room was only 300 yuan when he registered using his friend’s account.
Later, many Internet users shared their experiences online, complaining that operators were often adopting price discrimination over their users, offering the same product or service at different prices.
