"It appears that the multi-million dollar episodes were protected by a mere watermark in the bottom left corner of the video, promptly blurred by the leaking group."

"The watermark is pretty much useless, Cauet reckons.  Instead, credits and scenes could have been minutely extended, with a different time-tweak for anyone getting an advanced copy.  Anyone planning a leak would need at least two sources to identify scene adjustments."
