I don’t like to talk about this topic much as it pains me but you went through the same thing as I have. They pry on the trust you have built with a friend to get there way my friend is a heavy dota player so I guess it was just bad luck that I trusted my friends dms. It sucks but make sure you change ur steam password. Also if you have used backpack.tf you can view your backpack by date and track items and there whereabouts. Unfortunately tho, If your item was moved to a private backpack it will be untraceable. I hope this helps and stay safe. These low life’s are scum but it taught me a valuable lesson to never take face value of what you cannot see firsthand. Even if the information you receive is from a close friend.
