I have a general question regarding a trade i just made and the way it went down with the user threatening to report me. I had my houwar listed on outpost after buying it a couple of months ago. When i bought it i was looking for a clean one and checked backpack.tf which it usually says at the top"this item is duped" or something along those lines. I checked this and it didn't say so then i went ahead and traded for it. I then decided to take offers on it and listed it as clean where i wanted buds or a clean hearts modest. Today i get an add and he tells me that he will trade his modest for the houwar and all was good. The trade went through and i checked the history after, Should have checked first but he wanted to trade straight away claiming he needed the money for a graphics card. The modest was duped and there wasn't anything i can do about it now as my add clearly asked for a clean one. What am i to do as the trade was done. About 2hrs later the person i traded with starts hurling abuse at me stating the houwar is a duped one and i tricked him into buying it. he wanted his modest back and even though i explained tyo him a few times i had done my cheks on it i missed that it was a dupe but somehow him trading me the duped modest was different and he didnt care about that. He wants to backtrade and i told him that i will keep the modest as i checked the houwar and it was a clean one but he clicked on every name in the list until he found someone else has the same item. How is it different in him selling me a duped modest when i clearly asked for a clean one to the houwar being duped also. Both parties agreed to the trade and neither checked before hand. I just wanted to check firstly that if he reports me i wont become marked?, having 5000 hours in tf2 that is the last thing i want to see and have never had an issue with any trade ever in the past. Can anyone advise as i believe we both should have checked the items first and i told him i wouldn't be trading back.
