Interestingly, Facebook keeps records of every single user you block, allowing you to see at a glance which users cannot contact you in any way via Facebook.
Bear in mind that Blocked users are not displayed in alphabetical order, but in the order in which you blocked them, from most recent blocking. When viewing your blocked users list, you can only take one action: unblocking that user.
