He sad his unusual hat has a 100% clean history . I searched on Outpost for a Hat with the same lv.
Nothing. After i made the trade i checked the history but there wasn't one. I wrote him about the duped Unusual, he deleted and blocked me at once. Also he changed his name. An other guy had him in his friendslist so he could send me his url. I have no screenshot. In the History of my Battlers the hat is still in my inventory but i doesnt exist. Mayby the guy manipulates the item historys. pls check that .

Thx for your help

Its impossible to manipulate historys, they are just bugged. Also, without proof it wont work, his profile is private which makes it even more harder, and that unusual is pretty clean theres only 1 owner and it isnt duped
