I'm not familiar with the item and the scam attempt, so its not really possible to comment upon without more information. How does one become eligible for the "Rust - Game shirt" ? and whats the attempt to scam look like? /edit: just looked at the report. I would have to conclude its more like a shark attempt then anything else. Traders should look into the items that are offered, and think about if they really want the offered items. If it doesn't fit into their knowledge area, don't trade for it. Valve's "Buyers remorse" rule would be the best way to describe it.
