Can I be blocked if iMessage says delivered?

I don't believe that if someone has blocked you that you will see Delivered, but I also believe that the Delivered does not necessarily mean the receiver has actually received the text, just that it was delivered through the system. You will never see any type of confirmation that you have been blocked either.

As of ios16.0 and higher, messages will show delivered even if you are blocked.

its apparent people aren’t reading the update changes beforehand

There will be absolutely no indication when someone blocks you. Yes, it will still show as "delivered" either way.

iPad has no SMS/RCS support, so all messages are either sent via iMessage and data — not happening to Android — or via an iPhone with Continuity to Android, or to anything devices when iMessage data comms are wobbling.

Also, if it says Delivered that doesn’t mean the recipient has read it😏

There is no difference visible to the sender normally or if they have been blocked.

If you think you’re blocked, stop sending.
