If someone is in your blacklist in WhatsApp, how do you know - briefly?

If someone is on your blacklist in WhatsApp, you will not receive any messages or calls from them. Additionally, their profile picture and status updates will no longer be visible to you.

If someone is in your blacklist in WhatsApp, how do you know - in detail?

If someone has added you to their blacklist on WhatsApp, there are several indicators that can help you determine this. Firstly, if you try to send a message to the contact and it remains unread with no delivery checkmarks (one gray checkmark for sent, two gray checkmarks for delivered), this is a strong sign that your messages are not being received. Additionally, if you attempt to call the contact and the call does not connect, or if there is no change in their last seen status even after they have been active on WhatsApp, these are further indications that you might be blocked. It's important to note that WhatsApp does not notify users when they have been added to someone's blacklist; therefore, the absence of usual interaction cues is often the primary method of identification.
