What happens when someone is added to your WhatsApp blacklist - briefly?
When you add someone to your WhatsApp blacklist, they will no longer be able to contact you or see your online status. Additionally, their messages and calls will not reach you.
What happens when someone is added to your WhatsApp blacklist - in detail?
When a contact is added to your WhatsApp blacklist, several changes occur that affect both parties' interaction on the platform. Firstly, any messages sent by the blacklisted contact will not be delivered to you and will remain undelivered in their outbox until they are removed from the blacklist. This means that the sender will not receive a read receipt or double-check marks indicating that their message has been seen.
On your end, you will not receive any notifications for messages sent by the blacklisted contact. Their messages will not appear in your chat list or any of your chats. Essentially, WhatsApp creates an invisible barrier preventing any form of communication from reaching you. It is important to note that adding someone to your blacklist does not delete previous conversations with them; those remain intact and accessible within the app.
For the blacklisted contact, their experience is somewhat different. They will see a single checkmark next to each message they send to you, indicating that it has left their device but has not been delivered or read by you. However, they will not be notified explicitly that they have been blocked; the app does not display any specific indication of this status change to them.
Moreover, calls from a blacklisted contact cannot reach you either. Any attempt to call you will fail, and the caller may hear a message saying the call did not connect or see a notification stating that your number is unavailable. This ensures that there is no direct communication between you and the person on your blacklist.
In summary, adding someone to your WhatsApp blacklist effectively cuts off all forms of communication from that individual. Messages remain undelivered, notifications are suppressed, and calls cannot be received. While the contact remains unaware of being blocked, their messages and calls will not reach you until they are removed from the blacklist.
