TL;DR - jump to the challenge at the end

====ON BLOCKING EVIL BOTS=====
On a resent job interview I had for "Incapsula" a few days ago I was put to the challenge to break
their bot protection mechanism. Apparently node.js is not that common among bot writes and most bots
are not able to run javascript.
The challenge had two parts -
1. find what the code does.
2. implement a bot that will break the code without using js.
3. think how to make this code unbreakable
