: If you can see their public profile while logged out but it becomes "unavailable" as soon as you log in, they have specifically blocked your account.
But wait—don’t panic yet. They could have simply deleted their account or switched to a “Hibernation” mode. To test this, open an incognito window or log out of your LinkedIn account. Search their name again. If the profile appears while you’re logged out but disappears when you log in… ding ding ding. You’ve been blocked.
: While old messages may still exist, you will no longer be able to send new ones to that person. In some cases, their name may change to "LinkedIn Member" in your inbox.
LinkedIn doesn’t announce “You cannot message this person because they blocked you.” It just leaves you in digital limbo.
