Can the risk control rules of an exchange be changed arbitrarily? Of course not. Recently, a user claimed online that their account was frozen with 40,000 yuan due to risk control measures, hoping that a leading trading platform would step in to unfreeze it. The platform later officially responded to this matter: If the buying and selling activities of an account violate the platform's terms of service, the platform will not compromise or make concessions due to public opinion. The underlying implication of this statement is clear — risk control measures are based on rules, not on public sentiment. To put it simply, if every time users are dissatisfied, the rules are changed, the platform's credit system would be completely broken. Users also need to understand that the risk control mechanisms set by exchanges are often in place to protect users' funds, prevent money laundering, and combat fraud. Of course, when it comes to why a specific account is under risk control, there must be a transparent appeal process, which is the key to balance.
