I don't think that there will ever be a substitute for due diligence and thorough credit investigation. Perhaps a load matching system that required stringent entrance qualifications would reduce the number of outright scammers and charlatans, but really, isn't the onus on the purchaser to check who they are dealing with, regardless of how they come to you? I think we would be fooling ourselves if we surrender that duty to any type of load matching system. It might be possible to devise a "high class" chicken coop, but the foxes will instinctively find a way in.
