Kind of an item duplication method here. This is how it works: You make two more steam accounts (assuming you already have one), wait until you are able to trade on both of the accounts, send the items to one of the other accounts you made, then send it again to the other one you made, then complain to Steam Support that your account and email got hijacked and your items are missing. Try to make it very convincing. Eventually you will probably get your items back from Steam Support (but the second account you sent the items to will still have the items as well). The first account you sent the items to will most likely be trade banned or banned. However, most likely your second account you sent the items to will not be banned. Allowing you to trade the items back to your main account.
Not sure if this is saturated or not so use at your own risk. I haven't tried it myself so I wouldn't know if it works, but I'm pretty sure it does.
