Sometimes, people tend to forget their passwords, or sometimes even login names, disabling them from accessing their own account, rendering it inactive. Getting your account compromised by someone else is a similar but a worse scenario, because someone else can do whatever they want under your name, but without your permission. Although facebook has established a very secure recovery procedure, it may occur that recovery does not always work. Many people have found it incredibly easier to hack into their own account to regain their access. This is referred to as black-hat recovery as it involves illicit means of retrieval, but with good intentions.
I, myself, would prefer this method because it does not take a lot of time and procedures. You would only wait for it to do the entire recovery process for you. This same procedure that is written in the tutorial on how to hack facebook passwords is used here.
