Unless Facebook releases usernames after deleting accounts (or you remember that this is indeed your Facebook ID) I think these are all different accounts. There is also another http://www.facebook.com/profile.php?id=100001554391855 which as well does not show your username.
The first comment on the post explains that the account in question appears to be set up by a spammer. It is an impersonation by a bad apple, not something Facebook did. Reporting it should result in its removal, hopefully.
If that doesn't happen, _then_ Facebook is responsible.
