You might be able to offer different levels of service based on the amount of information you are making the transaction with. Quite possibly small trades for unverified. Larger amount for verified and even larger for verified and photo ID or something like that.
Marks, thanks for the suggestion. Your invite is on its way.
We're actually in process of making a decision on new member policies and restrictions. It's obvious now that we have to offer something to new BitCoin community members. Most probably, that's going to be a fairly limited access with restrictions removed upon identity verification. Within several days there'll be a correpsondent notification to all members once marketplace engine is capable to enforce restrictions based on trust level.
For now we have several options to recognize definitely trustworth traders:
1. #bitcoin-otc WoT (web of trust) rating. You're also advised to mention the #otc username under 'About' section.
2. Tradehill rating. You're also advised to mention the #otc username under 'About' section.
3. Personal identity document scans (state or federal), confirming your name, age and address + 0.10$ paypal charge in order to expose confirmed billing/shipping address. Address on identity documents should match one used in paypal.
As always, suggestions are highly welcome here.
