This always makes me wonder...
The whole reason that the Norks general population isnt permitted the internet is to try and hide the realities that the rest of the world is not starving worse then they are and to maintain the belief that North Korea really is the shining beacon of humanity that their glorious leaders say they are.
But if you take 3000 people and task them with trawling the internet for things to attack and they will pretty quickly see that their leaders are full of sh*t (half an hour on Youtube should do it!). Now you can probably sweeten the deal for those 3000 by giving them access to everything, great pay, etc but eventually someone is going to let slip the truth to family members, who let slip to neighbours and before you know it an entire town is going to be aware that things arent quite as rosy as they are being told they are. At that point, keeping the word from spreading further is not going to be an easy task.
Add to that, that even the most basic script kiddie has to have some level of intelligence and so when confronted with evidence like that, they have to begin having second thoughts about the bollocks spewing from the "Great Leader" and you wonder why such info hasnt spread through the masses more widely.
I'm not suggesting that this army of 3000 doesnt exist but I'm also aware that people cant keep secrets (especially not 3000 script kiddies!), which makes me wonder how the Nork general population doesnt know more about the rest of the world. And why there isnt more of an outflux of people fleeing the sinking ship that is North Korea?
