Well something like this in impossible if you are to really think about it, because the problem lies here in the fact that you can't be anonymous when handling a lot of the LBC exchange things which include stuff like bank transfer, credit card selling, etc. These are all transcations that you have to be known for, you have to provide some sense of identification or people are just not going to use you -- as this is an easy way for scammers to try to cash out with their stolen CC's and bank stuff.
Plus the fact that KYC regulations exists, which force companies into intruding into the privacy of their customers.
Thanks for the comment. Right, depending on what you are offering for trade you can compromise your anonymity. The point here is not just in maintaining anonymity in exchanges, but making a decentralized p2p exchange in the blockhain itself which has many advantages including "automating" the conversion of your coins (done by a wallet) as well as preventing governments from shutting down or getting your personal info from exchanges. If privacy is very important to you then you probably don't want to ship anything or offer bank transfers in this system. Scams can happen but the new feedback functionality and also the factors of how long a wallet has been around, how many blocks it has mined, how many transactions it has made, etc. will not only help you determine if a person is worth risking trading with, but also it could be set up that certain addresses are trusted by a consensus of people or your wallet will look for x y z criteria to determine trustworthy wallets. The sky is the limit with the possibilites.
