I have done some digging around looking for something that could link Zedicus to his account. I have done some business with him in the past, as he participated in a group buy I did a while back. Here is a link to all of the transactions in the group buy which were done about a year ago: https://bitcointalk.org/index.php?topic=268280.msg2869200#msg2869200

Zedicus' transactions include the following Bitcoin transaction IDs:


All transactions done with him involved the Bitcoin address: 1Mc6bbZKwthrCWgtwa7yGsADKAqoNNza5L

Assuming the real Zedicus still has control of this Bitcoin address, we could have him sign a message proving he owns the private key for that address.

Hope this helps!
