Particularly relating to drugs and prostitution various governments around the world tend to work together to take action against high profile targets. Often the only purpose of this is for good news coverage for the governments involved (the recent action against the farmers market operating from the Tor network as an excellent example).
I believe that there is no better method of getting GLBSE shut down and it's operators jailed (i.e. me) than to allow "vice" assets to be listed or traded. I believe this represents an incredible risk to GLBSE.
I believe in the free market, I also believe that participants in the market may do so on their own terms.
I don't think choosing a jurisdiction to operate under is the correct choice for now, I think that should be done only when it has to (or when GLBSE can afford to).
I also don't think that GLBSE should spell out what is and is not allowed, because as has been mentioned by ColdHardMetal this will leave loopholes that we will forever be plastering over.
I think the suggestion by Blitz, that new assets can be created and listed on GLBSE, subject to our approval is a good one and is the option that I would put forward. It would also mean that we don't have to specifically spell out what we will or won't approve.
I would like to see added to this that any currently listed assets would also be subject to this, this would prevent an existing asset being bought out or used as a method to get around our requirements. (opinions on this point welcome)
From a practical perspective this would mean that the shortest time an asset could launch would be three days, giving plenty of time to have a look at any new proposals.
Regarding the legality of prostitution and drugs, it's a very touchy subject. GLBSE is not the SilkRoad (which has remained entirely anonymous). With the exception of tobacco and alcohol (both heavily regulated almost everywhere) almost every jurisdiction on the planet has banned drugs (a few allow cannabis).
Prostitution is legal in some parts of Germany, Austrailia and a few mother places, many other places (such as Thailand) have laws against prostitution (i.e. it's illegal) which are almost never enforced.
Rather than trying to figure out how to walk such a tightrope as others throw things at you (you can be sure, despite the legality of any of these sorts of activities based on jurisdiction, the main stream media would have a field day), I think we should just avoid it altogether.
It's a far too dangerous and messy area that I would like to see GLBSE avoid.
I think this is reasonable. Far better for GLBSE to stay out of the dangerous limelight by enforcing some basic regulations. If GLBSE got slammed with the kind of media backlash Silk Road has, I doubt it would survive, or survive in a way that was useful to the network. I doubt many projects affiliated with blatantly and widely illegal "products" would use a non-anonymous exchange in any case.
The way I see it, banning drug and prostitution-related enterprises will greatly help in keeping GLBSE out of the negative media spotlight and make it much less likely to be a target for law enforcement. The few people it would hinder shouldn't be using a public exchange anyways.
