Whatsapp has been hacked, can you still send messages to each other?

Whatsapp has been hacked and can send messages to each other. But these messages may be blocked by the other party, and even if they are sent, the other party may not receive them. Because if your number is on the other party's blacklist, the other party's mobile phone may block all the information and incoming calls you send and stop contacting you. However, using other numbers or sending anonymous short messages may have some disadvantages, which may aggravate the contradiction between you once the other party finds out. WhatsApp is an application for communication between smartphones, which supports iPhone and Android phones. With the help of push notification service, this application can immediately receive messages sent by friends, relatives and colleagues.
