I have never traded with this idiot. But I felt the need to place neg rep on his page for all to see since he can't keep closing threads in hopes of hiding his scams.
He is a troll and abusive. He puts neg rep on random people he has never traded with and wastes people's time by agreeing to a trade only to continuously attempt to change the deal for ever increasing value items. He will waste your time and troll you. I already reported him to my contact on SG and on Steam as well.
Apparently he is regifting his wins and using his current giveaways as trade material as well with no intent to trade. I cannot express how much you should NOT trade with this person.
He even left neg rep on a fellow trader that has never even heard of him , much less traded with him. Seems to be just some very sad troll.
