Can a blocked contact see that they are blocked in WhatsApp - in detail?
When a user blocks a contact on WhatsApp, the experience for both parties changes significantly. The key aspect to understand is whether the blocked contact can discern that they have been blocked.
Firstly, it's important to note that once a contact is blocked, they will no longer see updates to the blocker’s profile picture, about information, or status updates. This can be an initial indication for the blocked user that something has changed, but it is not conclusive evidence of being blocked.
Secondly, messages sent by the blocked contact will never be delivered and there won't be any checkmarks (one gray, two gray, or two blue) next to them. This lack of delivery confirmation can be another clue for the blocked user that their messages are not reaching the intended recipient. However, this could also be due to other reasons such as the blocker having their phone turned off or being disconnected from the internet.
Additionally, calls made by the blocked contact will not go through. The call will show a "ringing" status indefinitely for the blocked user, but it won't actually connect. This persistent ringing without connection can also hint at being blocked, although it might be mistaken for network issues or other technical problems.
Another telling sign is that the blocked contact cannot view the blocker’s last seen or online status. If the blocked user tries to check these details, they will see no information available, which can be a strong indicator of having been blocked.
In summary, while there are several indicators that can suggest a contact has been blocked on WhatsApp—such as undelivered messages, unsuccessful calls, and lack of profile or status updates—WhatsApp does not explicitly notify users when they have been blocked. This ambiguity is by design to preserve the privacy and safety of those who initiate the block.
