How does 6s prevent spam messages like Taobao?

You can use Tencent Mobile Manager to intercept this, open Tencent Mobile Manager-Security Protection-Harassment Interception, and blacklist all the called numbers. This will prevent these numbers from harassing users by calling again. Finally, the ability to "report" intercepted harassing calls can improve the accuracy of interception by Tencent mobile phone housekeeper and make "intelligent interception" more reliable.
