If you block a contact in WhatsApp and delete it, what happens - briefly?
If you block a contact on WhatsApp and subsequently delete the chat or conversation with that user, the block remains active. This means the blocked individual will still be unable to contact you or view your profile picture, status updates, or any changes made to these elements after they were blocked.
If you block a contact in WhatsApp and delete it, what happens - in detail?
When you block a contact on WhatsApp and subsequently delete their number from your contacts list, several changes occur within the app's ecosystem. Firstly, blocking a contact prevents them from seeing your online status or any updates to your profile picture. This means they will not be able to view when you were last seen active or any changes in your display photo. Additionally, all messages sent by the blocked contact will not be delivered and will remain undelivered on their end. You, however, will still see their messages in your chat history until you manually delete the conversation thread.
Deleting a contact after blocking them does not remove the block itself; the block remains active. This means that even if you decide to add this contact back to your phonebook at a later time, they will remain blocked unless you explicitly unblock them from within WhatsApp's settings. It is important to note that the blocked individual cannot call you or send you messages through WhatsApp. If they attempt to do so, their messages and calls will fail to go through.
Furthermore, any groups that both you and the blocked contact are part of will not be affected by this action. The blocked contact will still see your messages and status updates within these group chats. However, you will not receive any messages or calls from them directly outside of the group context.
In summary, blocking a contact on WhatsApp followed by deleting their number results in a situation where the contact is completely restricted from communicating with you through the app. The block persists even after re-adding their contact information, ensuring that your privacy settings remain intact until you choose to alter them.
