Steam, Valve’s digital gaming platform, affirms that they won’t be helping people that have been victims of trade scams with recovering their stolen items, the reason being:
“Our community assigns an item a value that is at least partially determined by that item’s scarcity. If more copies of the item are added to the economy through inventory rollbacks, the value of every other instance of that item would be reduced,” explains Steam’s policy.
We sympathize with people who fall victim to scams, but we provide enough information on our website and within our trading system to help users make good trading decisions.”
So, you don’t really need to hurry that much about it – unless you’ve already been scammed -, as Steam provides to people a huge variety of options and advices that promise to help them in making future deals with other people that are interested in exchanging some valuable – or not that valuable – items.
In the end, is all up to us, Steam users, to avoid getting scammed
