But don't think that this market solution will make the breakthrough: A remark points out that the contents of shops or their owners can be censored. - Something that the crypto world should actually overcome.
How can you be sure double deposit escrow will not make a breakthrough?
If you want a private market then just make it private in the listing and it will be invisible to all but those you give the link to.
I agree that the centralised censorship should be totally removed, I don't think there should be any single point of accountability with a trustless decentralised solution i think it makes it dangerous for the persons with moderation powers.
The entire point of a DDE marketplace is really to make it 100% trustless and automated with no central points of accountability.
However it could be that flagged seriously messed up adverts can be removed via a decentralised voting process since we already have decentralised voting built into bitbay. I think they would have to be seriously illegal and undesirable to most for them to bother voting them off though. Most people are not going to bother voting off things that are grey areas or things that are not universally recognised as offensive. It would take a bit of planning.
Give David time to answer your questions. He usually answers very quickly he must currently be very busy working on something.
