Will the person see anything if I block them on WhatsApp - in detail?
When you block someone on WhatsApp, there are several changes in the interaction between your accounts that both parties should be aware of.
Firstly, it is important to understand that blocking someone on WhatsApp does not completely remove their visibility from your contact list or prevent them from seeing certain information about you. The blocked individual will still be able to see your profile picture, status updates, and any changes in your 'About' section until they decide to block you as well. However, once you block a user, they will no longer be able to send messages, make calls, or view your stories and status updates. This means that while the person will still see some aspects of your profile, their ability to interact with you is significantly restricted.
On the other hand, if the blocked individual tries to communicate with you—whether by sending a message, making a call, or viewing stories—they will encounter restrictions. Their messages will not be delivered and they will receive a notification stating that their message was not sent because their contact has changed their number. Similarly, any calls they attempt to make will go unanswered, and they will not see any updates related to your status.
In summary, while blocking someone on WhatsApp does limit their ability to interact with you, it does not completely hide your profile information from them. They can still see certain aspects of your public profile until they take similar action against you.
