Deleting a Facebook account was never an easy task. To do that, several email exchanges were needed to be do account deletion (removal of all records from Facebook server permanently).
Now, Facebook has made account deletion easier. An option is now available in Facebook for account deletion. Facebook has even added a "How do I delete my account?" in its help section.
I quote the below from Facebook:
"If you deactivate your account, your profile and all information associated with it are immediately made inaccessible to other Facebook users. What this means is that you effectively disappear from the Facebook service. However, we do save your profile information (friends, photos, interests, etc.), so if you want to reactivate at some point, your account will look just the way it did when you deactivated. Many users deactivate their accounts for temporary reasons and expect their information to be there when they return to the service.
If you do not think you will use Facebook again and would like your account deleted, we can take care of this for you. Keep in mind that you will not be able to reactivate your account or retrieve any of the content or information you have added. If you would like your account deleted, please contact us using the form at the bottom of the page and confirm your request in the text box."
