Hi, I'm not a Mod but I can say this is a bit confusing right now.
You are reporting https://backpack.tf/profiles/76561198856405383 "dobosito"
who doesn't have TF2 Inventory (only CS:GO)
You mention the name of this guy
https://backpack.tf/profiles/76561198418291842 "AyeD!mus | hellcase.com"
who doesn't seem having an Unusual for sale.
Maybe you could try and find the account that you were going to trade with?
And look through you sent/received offers for more information?
I just want to make sure your Steam account is not compromised
