Send a message after hacking, can the other party receive it?

Can you receive the message sent after the blacklist?

can

If blackmail is just a one-way blackmail, you blackmail the other party and then send a message to the other party, and the other party can receive it, but the other party can't send you a message anymore.

All mobile phones have blacklist function. If you don't want to accept phone calls or text messages from the other party, you can blacklist the other party or set blacklist rules. Just don't answer the other party's phone, and you can also set the ability to receive short messages, but most of the blacklist functions just can't receive the other party's phone calls or short messages.
