09Why did the e-sports platform send me a verification code?

The mobile phone number was leaked. The reason you received a verification code text message is because your mobile phone number was leaked and used by criminals to continuously send verification codes and other spam text messages to your phone number within a short period of time. You can try to use third-party mobile phone manager and other software to set up harassment interception and reduce harassing text messages or calls to the police as much as possible.
