Sorry that I ask so much questions,I'm new to unusual trading and trading with banned people
his name is HITMAN in my friends if you wanna check his steamrep

Here's a guy who wants to buy my unusual,but it says he is trade banned in Steam,but he says he can still trade,and I don't know if that will make me a scammer or something like that in SteamRep or tf2OP. You can see him in my friends list: THE TRUE JOHN | trade.tf if you want to check his steamrep
