According to Stats.tf there is less than 1 refine metal per account in tf2, how is this to much metal? I do not argue that the idle account explosion had an impact but to me the main reason for keys increasing and items (hats/misc) decreasing is the fault of backpack.tf, and their TOTAL lack of rules. They allow anyone who can type to submit a price change, using outpost and other sites as proof. These sites only show offers to sale and offers to buy but not what the item sold for. This is flawed in more ways than can be counted. Worse yet is allowing an item to have an potential price change every day of the week. Another issue is the ranking system in which many players compete to have their price suggestions approved, so they can move up in the rankings. Another issue is time limits before approval, there isn't any, I have seen admin accept/approve changes that have only been up for just over 1 hour. All this combined, leads to an out of control price manipulation system for a site that washes its hand of any responsibility. The site is responsible, not because of what it does but because the majority of players in TF2 treat backpack.tf as the authority on pricing, backpack.tf is the site setting the prices, not the players.
