Will the person know if I block them on WhatsApp - briefly?
When you block someone on WhatsApp, they will not be notified of your action. However, they may infer it based on certain changes in the conversation status or their messages not being delivered.
Will the person know if I block them on WhatsApp - in detail?
When you block someone on WhatsApp, the experience for the blocked user is quite subtle and may not immediately raise suspicions. The primary indication they might notice is that your profile picture will no longer be visible to them. Additionally, any changes to your status updates will also cease to appear in their app. However, these changes are relatively minor and might easily go unnoticed unless the blocked user is particularly attentive or specifically looking for such signs.
It's important to note that messages sent to you by the blocked user will not be delivered, but they will not receive any notification indicating this failure. Instead, the message will appear as if it has been sent but not yet read. This can lead to confusion on their part, especially if they are used to seeing immediate delivery confirmations or read receipts from your conversations.
One of the most significant changes for the blocked user is that they will no longer be able to call you through WhatsApp. If they attempt to make a voice or video call, it will not go through, and they may see an error message indicating that their call did not connect. This can serve as a more explicit hint that something has changed in your communication status.
Overall, while blocking someone on WhatsApp does provide certain indications that the other person might notice, these signs are often not immediately obvious or conclusive. The user might suspect something is amiss based on the lack of updates and call failures, but they will not receive a direct notification informing them that they have been blocked.
