If I block a contact on WhatsApp, will they see that I am online - briefly?

When you block a contact on WhatsApp, they will not be able to see your online status. This is because blocking a contact effectively removes them from your contacts list, preventing any visibility into your online activity.

If I block a contact on WhatsApp, will they see that I am online - in detail?

When you block a contact on WhatsApp, the primary goal is to prevent them from seeing your status updates and messages. However, the question of whether they can still see if you are online is one of frequent inquiry. To address this comprehensively, let's delve into the technical aspects of how blocking works on WhatsApp.

Firstly, it is essential to understand that when you block a contact, their messages will no longer be delivered to your phone. Consequently, they will not receive read receipts or online status updates from you. This means that if someone you have blocked tries to send you a message, WhatsApp will inform them that the message was sent but not delivered.

Secondly, the visibility of your online status is directly tied to the delivery of messages. Since blocking prevents message delivery, it also stops the transmission of your online status to the blocked contact. This ensures that even if you are actively using WhatsApp, the blocked contact will not see any indication that you are online.

Furthermore, when a contact is blocked, they are effectively removed from your contacts list within the app. This removal means that their attempts to interact with you, whether by sending messages or checking your status, will be futile. As a result, there is no way for them to see if you are online unless you unblock them and they manage to establish contact again.

In summary, blocking a contact on WhatsApp effectively hides your online status from them. They will not receive any indication that you are active on the platform, ensuring a higher level of privacy and control over your interactions.
