What Happens When You Unblock Someone — On Facebook Better

But perhaps the most haunting thing about unblocking someone is what it reveals about memory. In the physical world, forgetting requires effort. You must avoid places, lose phone numbers, resist the urge to ask mutual friends. Online, forgetting is the default. The algorithm does it for you. Yet when you unblock someone, you are not restoring a relationship. You are restoring the possibility of noticing each other . That is all. Facebook does not send a friend request. It does not suggest you message them. It simply removes the barrier and waits.
