Beware this Scammer!
He gave me a duplicate Key of Dishonored in a barter-Trade.
*He acted with a key from another trade. Screenshot 1 & Screenshot 2**
First he apologized. Later he made insulting references.
Ok, I'm overreacting a little to his "can u give me one day to get another key?" and later he started to make me insinuations (to the end of Screenshot 2). He asked me several times to get a new key. But he does not understand that I have already given him 24 hours for it. Later I asked him only for an alternative key to solve this problem.
It is also strange that he has xtimes ETS2 and Insurgency traded successfully in the past.
here 1
here 2
here 3
here 4 (later many more)
Maybe he buys and sells from grey market like G2A!!
Howsoever, he acts with keys that are known at least 2 or more people.
CAUTION: Let him only go first in higher trades!!
