Does anyone have an on going trade with him?
He sent me a bull message about how he was going to rebuy the cards and send them since they had not arrived after 4 days. I told him to hold on, it normally takes a few days....
He never responded, and then 3 days later I asked him if my cards were actually coming... And he hasn't logged in since Apr 3rd.
Basically writing off the trade now.
Just add him to the untrustworthy section at the top. You might want to write something like what MikefromPluto did. You can also post it to your trusted trader post if you have one. It is up to everyone else to search for people who may or may not be trusted.
