I use Mechanical Turk for many projects. It is a fast, easy, cheap way to get work done. I use it for content generation and research work. But there has to be some decent BlackHat exploits. Just in case you have never heard of Turk, it is an online marketplace where people can offer payment for businesses and services that require a human element rather than computing power.

How to harness it in a BH way is the question. You would have to be creative how you do it because Mechanical Turk clearly states you can't have people click on ads. Maybe there is a way to do it via GodCPA? I don't know. What do you think?
