Why did Gan send the verification code?

It may be the verification code at the time of registration.

If it is registered in the last few days, it may be that the system is stuck, resulting in a delay in sending. If not, pay attention to personal privacy, which may be the disclosure of personal phone number. You must pay more attention to information security when surfing the Internet.

If sending text messages for a long time has affected your normal life, you can try to set up harassment interception by using third-party mobile phone housekeeper and other software to minimize harassing text messages.
