Smooth makes solid points, but as I already argued upthread, nobody is willing to actually navigate the illegal/evil marketplaces on the deep web to check for BCN's presence.

If BCN is in fact used for black trade (snuff films, illegal pornography, etc.), how much of that do you think would really surface to bitcointalk?

Bytecoin is the result of careful production and has too much utility to simply be a premine scam.  My personal opinion is that BCN is definitely used for something, but nobody will come out and say exactly what that is without taking great risk.
