I wonder what untouched, anonymous, verified accounts for sites like Okpay/cashU/MtGox/Aurumxchange would be worth?
By untouched&verified i mean: these are not hacked accounts, i signed them up*, there is zero balance in them, the accounts are verified by email, phone, copy of a legal id and further name/address proof that got accepted by the sites. So these accounts have much higher withdraw/send limits than unverified accounts. Something like that should be worth something on the black market....
Any offers?

*This a theoretical discussion, I have no accounts for sale!
...but i'm really wondering if there is market for that,
since i only know the infamous site for weed&drugs.
I hope the exchangers track the black markets...
Yup, but also illegal due to identity theft laws in most western countries. Very probably against the EULA from the relevant exchange, so they can block your account if they find out. And ripe for scams due to the Id holder just contacting the exchange and claiming that you hacked the account after you transferred money/BTC into it. Why bother with it when you can just open multiple unverified accounts?
