To protect user privacy, imo doesn't notify
you when you've been blocked, nor can we
confirm whether a specific user has blocked
you.
However, you may notice the following signs:
● Messages show as sent but not delivered
(single blue check mark).
● Voice or video calls go unanswered or fail
to connect.
● You no longer see updates to their avatar.
● Their online status or "last seen" time is
no longer visible.
● Some of their profile, Story album, or
VoiceClub information is no longer visible.
● You cannot add them directly to a group.
● You cannot share their contact card or voice
messages.
If you see all of these signs for a contact,
it's possible you've been blocked by them.
However, these signs can also happen for
other reasons.
Please note that for privacy reasons, imo
cannot inform you if you've been blocked,
identify who blocked you, or remove you from
another user's block list.
