How to protect our privacy? China is not good in terms of privacy protection, we receive the garbage short messages and calls frequently.I received a ad call today. I donot know how they have my cellphone number. There are so many websites and companies donot protect their clients privacy. Even some of them sell clients' informations to others who want to sell things or do fraud.This behavior is illegal, but it's hard to find evidences for law enforcement agencies, so network swindlers are rampant. This problem has been troubling us, hasn't it?
