If I can make sure that passwords are securely stored and nowhere available in plain text even for hobby projects that will never see real users, how can Facebook with allegedly the top developers not make sure the same thing? And if you log something like this then everybody that ever saw these logs should be alarmed and press for changing that. Inexcusable to ever have that going on for more than 2 minutes. In 2012 Facebook was not a small startup with just Zuck zucking along.... This company is just so bad.
