What's new?
The gullible will believe what they are told without question, just as they have since the dawn of time.
This issue is not new, formerly if it was printed in black and white it was fact, when it wasn't always and still isn't. The 'fact' that the information contained in the internet is less reliable, even than the printed word, ought to be abundantly obvious to everyone using it.
Of course everyone should act like a typical El Reg reader and trust nothing, ever. (citation needed)
