Trade history : http://steamcommunity.com/profiles/76561198098692393/inventoryhistory/
My steam link : http://steamcommunity.com/profiles/76561198098692393
My friend : http://steamcommunity.com/id/s8lfish/ ( my middleman, he is my friend in real life too)
The scammer : http://steamcommunity.com/id/3643274575Q (scammer’s 2nd account, acting as my friend(middleman) , he changed his name)

The story :
1.I sell item to people and usually my friend (http://steamcommunity.com/id/s8lfish/) will be the middleman. So, on 22/01/2014/ the scammer (http://steamcommunity.com/id/hammerindustries/) wants to buy these Dota2 items : - Crest of the Magus Magnus, Bracers of Profound Perfection, Cape of Arcane Artistry, Unusual Captain Bamboo(orbitay decay ,brusque britches beige), Inscribed Hood of Endless Intellect, Golden Reel Guardian Totem, Frozen Golden Reel Guardian Helmet.
2.Next, at the same time he have another steam id in my friends list which is ----> http://steamcommunity.com/id/3643274575Q acting as my friend(middleman) , he changed his name and made the trade with me.
