Traded me a duplicated cadavers cranium for my mod pile of hats, 7metal, strange grenade launcher, fast learner, founding father, and other items. I've been scammed. I'm just a beginner trader =\.​

Screenshots:
I was too late to take screens of chat since the trade occurred 5 hours ago and I realize now I was scammed. I have screens of my inventory history and tfitems confirming the item doesn't exist. Is there a way to fetch trade chat?

Description: He traded me a duplicated cadavers cranium for my mod pile of hats, 7metal, strange grenade launcher, fast learner, founding father, and other items and I didn't find out until 5hours later.. I've been scammed. I'm just a beginner trader too ugh=\.

I am not a mod or admin here, but from what I can see on backpack.tf and tf2items, that cadavers does not appear to be duped.

Also, the admins here would need to see whatever trade agreement you had, specifying if he was indeed offering a doped one. But unless there are other sites (and I would like to know myself where to look) this hat appears top be clean. While one of the previous owners does have a listing for it on backpack.tf, it isn't in his backpack. He probably did not close out his trade offer.

And while it is only my opinion, the trade is pretty much equal......but again, that's just my opinion.

*Update

tf2items.com was down across the board. Please delete post.

Archiving, not enough evidence, also item was not duped.
