The way to build the market that will attract the most users is to build in owner/admin accountability in some way. Of course there will always be the LE element to deal with, and their resources are significant, but there has to be accountability for the people who own/run the market.
There needs to be a transparency that cannot be thwarted. Maybe have a way for a group of diverse, non-competing, highly reviewed, and meticulously vetted vendors, and select, long-established and well reviewed buyers to be given some sort of collective authority in the event owners or admins go radio silent during times like the last weeks of Abraxas. Require the group's approval of large or numerous wallet withdrawals within a short span of time, and then there could be a system wherein this same group of users were alerted by potential scam behaviors from an aggregate of information from wallet withdrawals, feedback, forums, and vendor inactivity. These users could then observe the suspect scammer and then submit their decision on whether or not to suspend, and the overall consensus of this group's votes would determine the outcome. Along with this, require a majority consensus of this group to be able to shut the market down completely for any reason. In the event of DDoS attacks or the like causing site downtime, have a spokesperson from this group whose sole responsibility during any unplanned/unannounced downtime is to get the word out to the necessary outlets. Have the code reviewed by Gwern, and alert him in the event of any unplanned changes to the code.
It would be somewhat user-policed, but the outcomes of "votes", and the transparency of the checks and balances would need to be reviewed periodically, and each user's behavior would be reviewed periodically as well, in order to assure outcomes that are for the good of the community. I know, sounds dreamy, it would be a fucking chore to develop, surely, and there would always be the constant threat of LE, but there needs to be a market that is not solely in the hands of a few buddies who are willing to abscond with millions of dollars without a word.
Ross is in prison for life without parole. To think market admins should have to take that risk on and have their opsec potentially impacted by having their decisions in the hands of babysitter council of drug traffickers who could suspend their powers of 'suspicious behavior?' fuck that.
There are already many methods of trustless or mostly trustless markets with some degree of objectivity rather than stroking the dicks of some elite 'council' who is probably more likely than the damn dnm admin to scam anyways.
