All of the members scammed by him are old time members such as myself. If you want to find them, John used to be a moderator here, BCB is a chat legend on Bitcoin freenode IRC channel #bitcoin-OTC and others can be asked through PM.

Trust me this was a situation where the whole community wanted him dead but no one had the power to do anything cause they weren't in the right place. At the time, the scam he performed was worth about $5000-$6000, I'm sure he has scammed for more at some point.
