No, a blocked contact cannot see your online status on WhatsApp. Blocking someone prevents them from viewing any updates related to your online presence or last seen time.
Can a blocked contact see if I am online on WhatsApp - in detail?
When you block a contact on WhatsApp, they are effectively cut off from any information about your online status. Here’s a detailed explanation of how this works:
Firstly, it's important to understand that blocking a contact on WhatsApp is a two-way street. This means that not only will you no longer see their messages or updates, but they will also be unable to view any information about your online status or activity. When you block someone, your profile picture, status updates, and last seen/online status are all hidden from them. They won't know when you were last online, nor will they see the typical indicators of your online presence such as the check marks that appear next to messages (one gray for sent, two grays for delivered, two greens for read).
Additionally, if a blocked contact tries to send you a message, it won't be delivered. Instead, they will see a notice indicating that their message was not sent. This further emphasizes the complete separation of communication and visibility when you block someone on WhatsApp.
In summary, once you block a contact on WhatsApp, they lose all access to any information about your online status or activity. This ensures that your privacy is maintained, and they will have no way of knowing if you are currently online or not.
