[PlayerName] is a scammer he won't put what he says in the trade and will argue you that it was there.
He's gonna let you belive that the most valued item is hidden behind the trash he put in!
If you see [PlayerName] with a 2x18 Resist 3x58, Its the item that he should have traded and had the most value.

I've already heard about another person that he tryed to scam him already.

Beware he might use other character to repeat the scamming he's just like that

Blacklisting is not allowed on this shard.

Well, so is scamming, but that's why there are such great systems in place to prevent it. Can you see the item, are you ok with what the player you're trading with has in his trading window? If so, click Accept.
By clicking accept, you confirm the trade. Whether you believe his story is another thing.
