When will a blocked contact see that I have blocked them on WhatsApp - briefly?

A blocked contact will immediately notice they have been blocked on WhatsApp as all messages sent to you will be displayed with only one check mark instead of two, indicating they have not been delivered. Additionally, your profile picture and status updates will no longer be visible to them.

When will a blocked contact see that I have blocked them on WhatsApp - in detail?

When you block a contact on WhatsApp, the immediate effects are noticeable to both parties involved. The primary question here is not just about when the blocked contact sees they've been blocked, but also how this action affects both of you in terms of communication and data visibility.

Firstly, it's important to understand that the process of blocking someone on WhatsApp is almost instantaneous from your perspective. As soon as you block a contact, several changes occur:

  1. Message Delivery: Any messages sent by the blocked contact will not be delivered to you. Instead, they will receive a notification saying "This message was successfully sent," but you won't see it in your chat list or inbox.

  2. Calls and Status Updates: Similarly, any calls made from the blocked contact will not go through, and you will not be able to view their status updates.

  3. Profile Information: The profile picture, about information, and last seen/online status of the blocked contact will no longer be visible to you.

However, the blocked contact may not immediately realize they have been blocked. WhatsApp does not send a notification to users informing them that they have been blocked by someone else. Instead, they might start noticing subtle signs:

  1. Message Failure: The blocked contact will see their messages as sent but never delivered. This can sometimes take a few moments to register, depending on the speed of their internet connection and WhatsApp's servers.

  2. Call Failures: If they attempt to call you, the call will not connect, which could indicate a block if it happens repeatedly.

  3. No Status Updates: They won’t be able to see any changes in your status updates or profile picture.

  4. Last Seen/Online Status: Your last seen or online status might disappear from their view, although this feature can sometimes behave inconsistently due to privacy settings.

Overall, while the blocking action is instant from your end, the blocked contact may take some time to notice and confirm that they have indeed been blocked. The absence of direct notifications by WhatsApp means that they will have to infer it from the lack of message delivery and other interaction failures. Therefore, it's a process of elimination for them rather than an immediate realization.
