If people read of a "h4x0r trick to read their bf/gf private messages", they will execute it. And hey, "it has this l33t keyboard shortcut that will make a strange window pop up, it must be what the hackers in the movies use!!". And then "Oh well, thanks to this friend of mine for sharing this cool trick that gives me the stuff to paste there, I would not know how to use it!". And finally "Booooo, Facebook sucks, my account got hacked".
I remember of the internet making fun of a girl that believed to be enrolled in some secret police because she popped up the Dev console. Well, that is just normal people, not uncommon.
I trust that actual developer can find their way around blocks and warnings, that however raise the bar for social engineering.
