Will the person know that they are blocked on WhatsApp - briefly?
When you block someone on WhatsApp, they will not be able to see your last seen or online status, nor will they receive any read receipts (blue ticks) for messages sent to you. However, they can still see when you are online if you start a chat with them.
Will the person know that they are blocked on WhatsApp - in detail?
When a user is blocked on WhatsApp, there are several indications and changes that occur which can signal to them that they have been blocked by another user. While WhatsApp does not explicitly notify users when they have been blocked, certain features and behaviors of the app will alter, providing clues about the blockage.
Firstly, if a person is blocked on WhatsApp, their messages will no longer be delivered to the blocker's phone. Instead, they will appear as sent but not delivered. This means that the double checkmark next to the message will remain gray, indicating that the recipient has not received the message. If a user consistently sees this behavior, it may suggest that they have been blocked.
Secondly, the blocker's last seen status and online status will no longer be visible to the blocked user. This information is typically displayed below the contact name in the chat window. When someone is blocked, these details will disappear, which can serve as another indication of being blocked.
Additionally, if a person tries to call the blocker on WhatsApp, their calls will not go through. The call will show as failing or unable to connect, providing further evidence that communication has been restricted.
The profile picture and status updates of the blocker may also become unavailable to the blocked user. If these elements are no longer visible, it could be another sign that they have been blocked.
Lastly, group chats can provide additional clues. If a blocked user is removed from a group by the person who blocked them, they will no longer see the messages or updates within that group. This change in group dynamics can also suggest that the blocker has taken action to restrict their communication.
In summary, while WhatsApp does not send explicit notifications about being blocked, the alterations in message delivery, status visibility, call functionality, and group chat participation can collectively indicate to a user that they have been blocked by another person on the platform.
