Everyone seems to be missing something.

Say they are very charming and managed to get free mining hardware, free cooling, free rent and a free giant 10mw data center. That's great, well done PB! It's still impossible to run 1 Gh/s for 5 years for less than a dollar in electricity alone in the cheapest country in the world.

This simple fact should end any discussion as to whether they're mining or not.
