Re: Blocking on whatsapp

If you do not get messages from that person

How can I tell if someone has blocked me on WhatsApp?
There are a couple of indicators that you may be blocked:
You can no longer see a contact's last seen or online in the chat window. Learn more here.
You do not see updates to a contact's profile picture.
Any messages sent to a contact who has blocked you will always show one check mark (message sent), and never show a second check mark (message delivered).
Any calls you attempt to place will not go through.


If you see all of the above indicators for a contact, this could mean that the person is blocking you.
