Next time you get scammed go to the police station they can help you out I know someone (Ryze Waterman) who reported a guy for hacking $650 and than running off with it they tracked him he is now in juvey and his parents had to pay the charges pressed against him. Doing that will get you're items stolen back and even some extra money after you press charges for theft or identity thief if they scam a email or paypal account. It is important you alert the authority's every time since you can redeem lost items and also prevent a (Noob) from being scammed I do not want any thanks or anything before anybody comes out and starts spamming and raging.
What if they are in a different country?
Your local police station would most likely laugh at you.
It never hurts to try I agree if there are corrupt officers there's more than 1 police station most likely in each city but I don't think that they will take it as a joke. If they do keep trying and if it doesn't work I think you would know by now to take more precautionary steps in trades such as using a middleman, making sure seller has full information on account being sold or another item, always send paypal other online payment companies etc..
