Your account has been frozen. \x0d\\x0d\ has been frozen: your account is suspected of being stolen. In order to prevent others from stealing, the protection mode is opened for you in security. In fact, the event that triggered this project was: sending bad information and deleting it after being intercepted by QQ Security Center. But personally, I don't think QQ has sent any bad information. In order to solve this problem in the future, please modify the QQ password. Click "Resume normal use". \x0d\2。 To enter the interface of unprotect mode, you need to edit the short message and send it to the designated number for verification, and the cost is ten cents.
