Imagine I got into those accounts like Ebay and Amazon and I had the ability to look around and buy things on your accounts with your money, wouldn't that be fun for me and you. I could buy anything from sexy lingerie to dildos with your money and I don't even have to send it to you because if you have other addresses saved like your wife, mum or your brother I could easily send stuff to them as a gift, from you... These sites only have a very small window where these orders can be cancelled, would you be quick enough? Would I allow you to access to your own accounts so you can cancel the orders? Probably not unless you do something for me and here lies the blackmail, what will I make you do to gain access to your own accounts so you can cancel those terrible orders I have placed..
