Reported flags for this user for violating the rules.

Trader backed out with just 2 days left to our trade. He doesn't even bother to explain why and just say to flag him as if flagging is no big deal to him. 

This guy stole my monster. I should have a trade with him: my PE dominion super for his ultra. I send him both trades, but he accepted only one, for super of course. After that he told that he didn't get my super, there was a bug, that's why he wasn't going to accept the second trade. I send a ticket to support twice, both times they checked his inventory and found my super in his storage. The trade went well accordingly. I told him about that and asked to give me back my super or accept the second trade, but he just stopped answer me.
Be careful with him, he is a liar! NEVER send the trades first, if you have a multiple trade with him. And check his trading history before accepting his offer - probably you can find the same mob in his another trades.

Doesnt response after 3 days!
