Does a contact see that they have been blocked and unblocked in WhatsApp - briefly?
When you block someone on WhatsApp, they do not receive any notification or indication that they have been blocked. Similarly, when you unblock them, they are also not informed of this change.
Does a contact see that they have been blocked and unblocked in WhatsApp - in detail?
When it comes to blocking and unblocking contacts on WhatsApp, the visibility of these actions can vary depending on several factors.
Firstly, when a contact is blocked, they will no longer see updates to your profile picture, about section, or any changes in your status. They will also not be able to call or message you. However, they will still see your last seen and online status until their next attempt to reach out, at which point these indicators will disappear. This is because WhatsApp does not send a notification or alert when someone blocks them; the changes are subtle and gradual.
Unblocking a contact in WhatsApp follows a similar pattern of invisibility. When you unblock a contact, they will not receive any notification informing them that they have been unblocked. However, once unblocked, they will regain access to your profile picture, about section, and status updates. They can also call or message you again, depending on your privacy settings.
It is important to note that while the actions of blocking and unblocking are not explicitly communicated by WhatsApp, there are some indirect signals that a contact might notice. For example, if they try to send a message after being blocked, it may show as undelivered or fail to send altogether. Similarly, if they were previously able to see your last seen status and it suddenly disappears, they might suspect that they have been blocked.
In summary, while WhatsApp does not provide explicit notifications for blocking and unblocking actions, the changes in visibility of profile information and the inability to reach out can serve as indirect indicators.
