Why do you just apply for WeChat plus friends and always send messages to be careful of fraud?

It is because the account just registered has not been authenticated by real name.

Real-name authentication is to bind micro-signals with your identity information. Simply put, you can find your ID information directly with this micro-signal. When there is no real-name authentication, it is likely that the capital exchange will not be able to track the whereabouts of funds, so it will show caution against fraud.

Benefits of wechat real-name authentication.

Real-name authentication can better protect the security of user accounts. The purpose of real-name authentication is to verify whether the account bound by the user belongs to himself or not, and to ensure that the funds in the account can only be withdrawn from the user's own bank card. At the same time, the payment password must be entered after the user's real name authentication. Once an abnormal transaction or fraudulent hacker attack is found, WeChat Pay will immediately intercept and quickly locate the flow of funds through the user's real-name information to ensure the safety of funds.
