As a Technologist in Information Security as I am, I go to my administration panel see if the member was really deleted or was suspended, as it must been, and, for my surprise, I noticed that all the information of this member was really gone. And that's wrong, that's really wrong.
In Internet, no information could be deleted, everything is important to everything.
Why did you think that Facebook don't allow the members to delete they account?
Well, it's only a tip for next update, I hope.
Besides it, there's everything simples awesome!
