If I block a contact in WhatsApp, will I be able to see when they are online - briefly?
When you block a contact on WhatsApp, you will not be able to see their online status. This is due to the privacy settings that WhatsApp applies to blocked contacts.
If I block a contact in WhatsApp, will I be able to see when they are online - in detail?
When you block a contact on WhatsApp, the primary goal is to prevent that user from contacting you or seeing your status updates. However, the visibility of their online status is more nuanced and depends on several factors.
After blocking someone, you will no longer be able to see their last seen status or online presence in the standard sense. This means that WhatsApp will not display their "Last Seen" timestamp or current online status under their contact information. Essentially, once blocked, their profile will appear as if they are not using WhatsApp at all from your perspective.
It is important to note that this does not mean you have no visibility whatsoever. If the blocked user is part of a group chat and they are active within that group, you may still see indications of their activity. For example, if they send a message or change their profile picture in a group setting, those changes will be visible to all members, including you.
Additionally, if the blocked contact tries to call you or send a message, WhatsApp will not notify you of these attempts. Their messages and calls will simply not reach you. However, there is no direct way for you to see their online status through normal WhatsApp functionality once they have been blocked.
In summary, while blocking a contact on WhatsApp significantly limits your ability to view their activity, it does not completely eliminate all traces of their presence, especially in group settings.
