It's still a wise idea to take it seriously. Many years ago, a then 17 y/o old ( German ) friend of mine did mitm on his own console in order to replace a video stream in ps home, recorded it for youtube/laughs. Not much later he was SWATed by the german police as if he was some kind of terrorist. His parents got a heart attack. Next he received financial death threats from a ultra expensive UK based law firm send by Sony.
