It will be difficult to get a dishonest reputation, because statistics gives the information on miners (http://en.dcoinwiki.com/Miner). A buyer and a seller should trust the same arbitrators. Which means that each and every arbitrator should earn not only buyers' trust but sellers' too. Eventually, I think, there will be a few respectful artbitrators, and most of buyers and majority of sellers will trust them.
