When Instagram shows someone as “Instagram user” instead of their name, it usually means their profile is no longer normally accessible to you. Most often, this happens because they have blocked you, deactivated their account, deleted it, or Instagram has removed/banned the account.
If you see “Instagram user” in DMs or on old comments, it means the account behind those messages or comments is gone or hidden, but the past activity (like the chat or comment) is still there. In some cases, you might briefly see “Instagram user” due to glitches or when someone is changing their username or has no visible name, but the most common reasons are blocking, deactivation, or deletion.
