Description:
I have noticed quite recently that I've found one of my TF2 item duped as I do remember that it wasn't duped when I bought it. I decided to go little deep and have done some research. His last activity on a trade website (TF2Outpost) was 8 months ago, and recently decided to sell his most valuable items for an expensive unusual (Link). I've checked the history of those; if you look closely the screenshots that I've provided, you will clearly see that 'ascending Item ID' on the list suddenly drops at the top. Backpack.tf also indicates that these items are duped recently. Please note that the Scammer owned this items 8 months ago (what a coincidence) legally in his backpack, thus this indicates he used 'Steam Support' to dupe these items.
I do believe these items are duped and unfairly released to the market without people noticing. I hope these proofs I'm providing are enough to mark this guy as scammer, or even trade banned(if possible, I'm not sure if you guys are able to do this). Thank you for reading and considering!

Hi, can you upload the screenshots directly to the steamrep thread via the "Upload a File" button located in the reply box at the bottom of this page and then post a reply with said screenshots, it'll make it easier for the admins to review this and to make sure 100% that it can't be deleted randomly to make space on the server if hosted on any other site. Reason they want you to do this is because if it's hosted on any other site it runs the risk of being deleted before the report is reviewed.

To be honest for this kind of situation, I do not need to put any screenshots since the direct links are the same as screenshots given (Item ID List/Previous Owners), just taking precaution to not getting this marked as 'Need More Info'; however if you think it will help to speed up the process, fine I'll upload to this reply.
