I just read about this scam as the title looked very interesting to me. It is nothing but a gift exchange scam. It works like this - if you present a gift worth $10 to someone (usually you get the contact in social media sites like Facebook) you may get 6 36 gifts in return. Isn't it an amazing deal? But as you rightly guess it's too good to be true and quite illegal too. The police warns us that you may not only lose your $10 in the process but your private information could also be compromised. So it is better to stay away from such offers.
