Yes, it should not be used for crimes. But we all are adult and everybody comes to his own decision.
However, I think crime advertisement is not the right way. There are to many idiots on this cybercrime train and do we want (more) idiots in this xst-community?
The basic idea with a stealthmarket where all goods can be traded is a good thing (imho) but we should not advertise with crime objects. Unfortunately this comes naturally.
