I frankly doubt that its used for much of anything (yet). No exchanges, no real "outside" buyers, etc. BTC worked/works for SR, etc. because you could take those BTCs that you sold your "stuff" for and use them for other things, and because people wanting to buy that "stuff" could buy BTC to use.

The idea that BCN is being used for some large evil economy defies logic.

I do agree that the developers might have what you said in mind when they (maybe) started two years ago, but it would have required BCN to succeed widely in addition to all that evil stuff. The evil stuff can't support an economy on its own. It didn't happen though, all that happened is a premine.
