If I block a contact in WhatsApp, will the subscriber see it - briefly?
If you block a contact in WhatsApp, the blocked user will not receive any notification indicating that they have been blocked. They may notice that messages are no longer being delivered or read receipts are not showing, but there is no explicit indication of being blocked.
If I block a contact in WhatsApp, will the subscriber see it - in detail?
When you block a contact on WhatsApp, the blocked user may not immediately notice that they have been blocked. However, there are several indicators that can alert them to this change in your communication status.
Firstly, the blocked contact will no longer be able to see your profile picture, your last seen status, or any changes you make to these elements. This is because WhatsApp restricts access to your information for users who have been blocked. Additionally, messages sent by the blocked user will not be delivered and will show only one checkmark (indicating that the message was sent but not received).
Secondly, calls from the blocked contact will not go through. If they try to call you, their call will immediately fail, further indicating that there may have been a change in your communication settings.
While WhatsApp does not send a notification to users informing them that they have been blocked, these signs can be quite revealing. It is important to note that the ability to detect being blocked depends on how closely the blocked user pays attention to these details.
In summary, while there is no explicit notification from WhatsApp, the inability to see your profile information, message delivery failures, and failed calls can all indicate to a user that they have been blocked.
