and please read the rest of the conversation... i don't know how much more transparent we can be about this topic... believe it or not, running an exchange is a serious business. Crypto is cutting edge and there are a lot of grey space in regards to what is legal or not. Most of that space carries a stiff fine and possible jail sentence (refer to bitinstant, silkroad, satoshidice). When our legal counsel, perkinscoie, who is a major firm in the crypto space, advise us not to do something. We listen. The FUD in here doesn't seem to grasp that concept.

The truth is that you can't control what people buy with any of the coins listed on your site. I think that is partially why this particular coins situation continues to be an outlier.
