What does the other party's message show after qq blacked out?

The other party has added himself to the blacklist, and his message cannot be sent. The hacked party will not be able to see their online status or send them messages. I won't hear from anyone being blackmailed, including Friend Request. This is qq to protect users' privacy and security and prevent hackers from receiving messages from hackers. But you can still send messages to other people's qq numbers, but these messages can't be received.
