Before any of you assume anything maybe you should directly talk to him about his bank so he can prove it. I've traded with him a couples time bulk order SSGP and still continue buying it.
As for the post above me the reason why he deleted you was cause you kept changing your mind about the items and kept lowering the prices wasting time. I was in the same chat as both of you along with the mod. It took 25 minutes for you to decide what items you wanted.
