Why does Taobao need to shut down its ID?

Basically, they are phishing for ID, or the social engineering database happens to have your ID account password, or they use 0day vulnerabilities. Your phone cannot be locked remotely. The ID lock itself must be turned on on the device you are currently using, and cannot be turned on remotely. Apple's imei modification can only be modified by jailbreaking, and it is useless to change it.
