What's the matter with qq plus friends waiting for verification?

Failed to pass the verification of the other friend, and was blacked out by the other party.

1, failed to pass the other party's friend authentication: the other party set "Authentication is required to be a friend", so when adding a friend, the other party received a message, but because he was offline, he could not pass the authentication, so he could not add it, and kept prompting to wait for authentication.

2, blacked out by the other party: blacked out is not a friend, adding friends again will always be displayed waiting for verification.
