Facebook-owned WhatsApp has done something to test this. Indicators Determine whether someone has blocked you on the messaging app. Keep in mind, however, that these indicators don’t guarantee that you can definitively confirm that a contact has blocked you.
How to find out if you have been blocked on Whatsapp
Checking Last Seen/ Online Status One of the easiest ways to check is by checking their last seen or online status in the chat window. You may not see the last scene because this setting may have been disabled by the user.
Checking for profile photo
If someone has blocked you on WhatsApp, you will not be able to see their profile picture. However, if you are able to see the profile picture of that person and you have been blocked in the meantime, you may not be able to see the updated profile picture of that user.
Sending a message to the contact
If you send a message to the contact who has blocked you, you will only see a tick mark after sending the message. You will not see the double tick mark and blue tick mark (read receipts).
Calling the contact
Attempts to call the contact may not be successful. When you are on a call, you will only see a calling message. However, this can also happen if the recipient of the call does not have an internet connection.
Creating a group on WhatsApp
If you try to create a group with a contact you suspect has blocked you, only you will be in the group when you go through the process of creating the group.
