If the other party blackmails you, will you get a text message?

Black messages can also be received, but they cannot be sent. If you hack the other party and the other party sends you a text message, but you can't receive it, the other party will prompt that the sending failed. Wechat messages can be received, but the other party can't see your message, but you can see the message sent by the other party. If you blacklist a person, the message you sent to the other party will not be received by the other party, and the other party will show that the sending failed or succeeded, but you can't see it, and the other party will prompt that the sending was successful. If you release a person from the blacklist, the other person can see the short message you sent, or you can send a short message back to the other person, and the other person can receive it. Blacklist means that you are not in the other party's friends, you can't see the message from the other party, and you can't receive the message from the other party. After blacklisting, the message sent by the other party cannot be received, and the other party will prompt that sending failed.
