A video has been posted to YouTube by a group called "DarkForum" in which plans for a card skimmer are demonstrated and a contact email for sales of said illegal device is listed. Screw these guys.
Let me reiterate: Card skimmers are not cute hacks or experiments. They're illegal devices used to steal money from innocent people, and anyone who makes, uses, buys or encourages the use of them belongs in jail. Tellingly, the first related video on YouTube is called "Pin Pad Thief Sentencing". I realise that by writing about these dorks I'm giving them publicity, but I'm hoping that publicity only results in something very, very bad happening to them. [YouTube]
