I would be interested in finding out why you would think for harm to be obvious? That’s the whole point to the harm that we speak of; to not be obvious, but ambiguous, hidden, an undercurrent, secretive, and that is only discovered on the in-depth study of it.
And if you might enlighten me on Facebook’s ‘good traits’?

Crack Book is famous for its gang stalking. There is organized skepticism, and atheism that the zealots take too as one would a religion. The controlled opposition in the major points. By is very nature of being a consensus of people who need to cluster in order to make themselves feel free… feel whole. Freedom is taken not given.

There are the controllers in each of the realities and sub-realities within the greater context and the super-duper reality of Facebook. Anything that cannot be censored, changed or manipulated…quashed or driven out by the status quo; anything that is controversial to the powers that be cannot reside within the freedom of Facebook.

Do you realize how much garbage has been collected into one spot of cyber space, its like a pacific current that endlessly circles that great ocean and  grabs and pulls into one place, plastic bits of every shape and size within a vortex of waters.

There are pages within Facebook, for most ridiculous mindset possible.
Facebook is a cancer in the internet, Facebook is the realization of everything pretentious and vile that society feels it thinks. Facebook is Barbifying of very young females.
Facebook is a mind control opera.

As far as marketers, there are no good marketers, and their henchmen the advertisers…well, I leave you with this quote from the great artist Banksy…

“People are taking the piss out of you everyday. They butt into your life, take a cheap shot at you and then disappear. They leer at you from tall buildings and make you feel small. They make flippant comments from buses that imply you’re not sexy enough and that all the fun is happening somewhere else. They are on TV making your girlfriend feel inadequate. They have access to the most sophisticated technology the world has ever seen and they bully you with it. They are The Advertisers and they are laughing at you.

“You, however, are forbidden to touch them. Trademarks, intellectual property rights and copyright law mean advertisers can say what they like wherever they like with total impunity.

“Fuck that. Any advert in a public space that gives you no choice whether you see it or not is yours. It’s yours to take, re-arrange and re-use. You can do whatever you like with it. Asking for permission is like asking to keep a rock someone just threw at your head.

“You owe the companies nothing. Less than nothing, you especially don’t owe them any courtesy. They owe you. They have re-arranged the world to put themselves in front of you. They never asked for your permission, don’t even start asking for theirs.”
— banksy

There are, of course, some good forums on Facebook where intelligent discussions take place, but that seems separate from the main “be my friend” model that makes Facebook, Facebook.

Facebook is also becoming the ultimate profiling device for marketers. This could be used for good or bad…

The free bird leaps
on the back of the wind
and floats downstream
till the current ends
and dips his wings
in the orange sun rays
and dares to claim the sky.

But a bird that stalks
down his narrow cage
can seldom see through
his bars of rage
his wings are clipped and
his feet are tied
so he opens his throat to sing.

The caged bird sings
with fearful trill
of the things unknown
but longed for still
and his tune is heard
on the distant hill 
for the caged bird
sings of freedom

The free bird thinks of another breeze
and the trade winds soft through the sighing trees
and the fat worms waiting on a dawn-bright lawn
and he names the sky his own.

But a caged bird stands on the grave of dreams
his shadow shouts on a nightmare scream
his wings are clipped and his feet are tied
so he opens his throat to sing

The caged bird sings
with a fearful trill
of things unknown
but longed for still
and his tune is heard
on the distant hill
for the caged bird
sings of freedom.
