Does the person you block on WhatsApp see it - briefly?
No, the person you block on WhatsApp does not see your message. Once you block someone, they are unable to view any updates or changes in your profile status, including messages sent after blocking them.
Does the person you block on WhatsApp see it - in detail?
When a user blocks someone on WhatsApp, the blocked individual will not immediately notice that they have been blocked. However, there are several indicators that can hint at this change in status. Here's a detailed breakdown of what happens:
- Messages: If the blocked user tries to send a message, it will appear as sent but will never be delivered to the person who has blocked them. This is because WhatsApp does not notify users when their messages are not delivered due to being blocked.
- Last Seen: The "Last Seen" timestamp for the blocked user will no longer be updated, meaning they won't see any changes in the other person’s online status. Instead, it remains static at the time of the block.
- Profile Picture and Status: The blocked user cannot view or download the profile picture, about section, or status updates of the person who has blocked them. These elements will appear blank or unavailable to the blocked user.
- Calls: If the blocked user tries to make a call, it will not go through and WhatsApp will show a message saying "This contact is unavailable." This applies to both voice and video calls.
- Group Interaction: If both individuals are part of the same group, the person who has been blocked can still see their messages in the group chat, but they cannot send private messages or make calls to the blocker within the app.
- No Notification: WhatsApp does not send any notification to the blocked user indicating that they have been blocked. The only way for them to find out is by observing the above-mentioned changes in their interaction with the person who has blocked them.
In summary, while a blocked individual on WhatsApp will not see an explicit notification or message stating they have been blocked, they can infer it from the lack of message delivery, the absence of updates to profile picture and status, and the failure of calls to connect.
