not only that you can forge a MAC address in a number of ways, such as configuration, or with a bridge, there are very tiny routers that fit in a cigarette pack or a coffee cup.
FB is the most insidious echochamber.
it reverberates so intensely, that any abberent waveslengths of thought are saturated and harmonically amplified to match the echo, and its a tuned echo chamber.
All of the fixes, and improvements are simply retuning maneuvers to match the propaganda of the day, I wholeheartedly believe that cuckerborg will go down in history as one of the most despicable thought criminals of this existence.
FB is a cancer 101% !
The biggest blackhat hack ever, FB and the mentality is propitiates is a threat to the real internet.
Everyone lives on thier browser because of facebook.
zuckerberg is a pedo, a blackhat, and an intellectual property thief. dont go playing the prove it cite it card, its right infront of everyones face, but the convienience is blinding all the old school users.
FWIW if you are under 30 you have never even seen the real internet, and that is the biggest crime, 3 cohorts of netizens think its a crime to use telnet, or FTP, or access internet functions with CLI.
smash the stupidity bubble and make FB die already .
