If I add someone to my blacklist on WhatsApp, will they know - briefly?
Adding someone to your blacklist on WhatsApp does not notify them. They will remain unaware of their inclusion in your blacklist.
If I add someone to my blacklist on WhatsApp, will they know - in detail?
When you add a contact to your blacklist on WhatsApp, the other person will not be explicitly notified or informed about this action. The functionality of the blacklist feature is designed to prioritize user privacy and control over their communications. Essentially, adding someone to your blacklist means that they will no longer appear in your contacts list within the app, but this change is only visible on your end. The other person continues to use WhatsApp as usual, without any indication or alert regarding their status on your blacklist. This feature allows users to discreetly manage their interactions and maintain a level of privacy that suits their needs.
