After looking at the two item histories, mostly at who the items directly to, I might be able to clear up confusion. The person who had taken the items either had a private inventory, or changed it to private after scamming the items, so that backpack.tf could not update the item histories through his backpack. Now as for the people who bought them, the guy with the $62,000 backpack is banned off Tf2outpost for trading with marked scammers so most likely he quickbuys off basically anyone. The bot is quickbuying scatterguns, and that's why it went to that bots inventory. What would really help out is if @CCDeVille could provide us his trade history and the scammers steam profile, if he still has it.
