How to determine that someone has blocked you on WhatsApp - briefly?
To determine if someone has blocked you on WhatsApp, check the status of your messages. If they are not delivered (indicated by a single gray tick) and the profile picture is no longer visible, it's likely that you have been blocked.
How to determine that someone has blocked you on WhatsApp - in detail?
Determining if someone has blocked you on WhatsApp can be challenging, as the platform does not provide a direct notification of this action. However, there are several indicators that can help you ascertain whether you have been blocked.
Firstly, check the last seen status and profile picture of the contact in question. If they have blocked you, their last seen status will no longer be visible to you, and their profile picture may not be updated or viewable. Additionally, if you try to send a message to this contact, it will not display the customary tick marks indicating delivery and read receipts. Instead, your messages will remain with a single checkmark, signifying that they have been sent but not delivered.
Another key indicator is the absence of updates in the person's status. If you are blocked, you will no longer be able to see any changes or new posts in their status. Furthermore, if you attempt to call this contact using WhatsApp, your call will not go through, and you may encounter a message stating that the call could not be completed.
It is also worth noting that if you are part of a group with the person who has blocked you, you will still be able to see their messages within that group. However, you will not receive any notifications for their individual messages or be able to start a direct conversation with them.
In summary, while WhatsApp does not explicitly notify users when they have been blocked, observing the absence of last seen status, profile picture updates, message delivery confirmations, and call connections can provide strong indicators that you may have been blocked by the contact in question.
