According to a report from FinCEN, the US Treasury Department's financial crime enforcement network, VIP users of Binance have been granted a series of special privileges, including advance notification in the event of a law enforcement investigation.In a 92-page order, the Treasury Department claims that Binance "developed a process whereby if a VIP user becomes the subject of a law enforcement investigation, they are notified," effectively monitoring its VIP customers.According to FinCEN, the process is relatively straightforward, with Binance VIP team members instructed to contact the investigated user through "all available means," including sending text messages and making phone calls to notify customers, for example, that their accounts have been frozen or thawed. FinCEN warned Binance VIP team members not to be too obvious in their notifications.The company told the VIP team: "Under FinCEN's order, we can't give a strong hint in any case and directly ask the user to run/exit, otherwise we will be prosecuted or held personally responsible. For example, your account has been unlocked/your account has been investigated by XXX, which is usually a sufficiently serious hint."According to FinCEN, Binance's internal reports indicate that in 2019, VIP customers "consistently represented two-thirds to three-quarters of the trading volume and revenue on Binance.com," and added that "therefore, Binance had a significant business incentive to do its utmost to support these VIP customers." Although rules prohibit Americans from trading on the platform, US users "represent an important part of the VIP user base" and sometimes account for 20% of all exchange fees.
