Nostalrius Begins - Quality wow vanilla realm (1.12)

Hello Nostalrius Staff,

I was just wondering why my account was just banned? I was in Orgrimmar on the character Diblae. I had just made a trade with a toon named Moomz or something similar. I gave him Thornstone Hammer(sp? lvl 37 mace) for 9g and was banned a few minutes after. I think there has been some sort of misunderstanding

Thanks
