What happens when I block someone?

 

When you block people on WhatsApp, you will no longer receive WhatsApp messages from them.
In more detail, here is what happens when you block someone:

• WhatsApp messages sent by a blocked contact will not show up on your phone and will never be delivered to you. Learn how to block/unblock a contact on: Android | BlackBerry | iPhone | Nokia | Windows Phone
• Your "last seen at..." and "online" information will no longer be visible to contacts you have blocked. More details about "last seen at..." and "online" can be found here .
• Any changes made to your profile picture will no longer be visible to contacts you have blocked.
• You will not be able to send messages to a blocked contact until you unblock them.

However, there are two important features blocking does NOT change:

• Your status message will still be visible to all WhatsApp contacts that have your number, including contacts you have blocked. Learn more about the status message feature here .
• Blocking someone will not remove this contact from your WhatsApp list, nor will it remove you from the list on this contact's phone. To delete a contact in WhatsApp, you must delete the contact from your phone's address book.
