i mean private listings would have to be broadcast by the listee if not integrated into search UI. I.E. you would have to find your target audience and risk discovery; private messaging people, using irc, or wherever to find customers. So if you sell something illicit or illegal (where you live) you are taking the risk of finding a customer outside of the UI to see your listing. You benefit from the escrow system and anonymization of transaction, but risk telling the wrong person about your illicit activities and risk discovery by authorities etc..
to me this seems like less liability for developers/average joe cloak person getting a onejury bounty.
this way we dont get authorities browsing all our listings all time looking for illegal activity and or entrapment issues?
