Anyone trying to buy counterfeit courses from these criminals deserves the viruses/keyloggers that end up on their machines.
This person is one of many counterfeiters from an crime ring in Singapore who will gladly take your money.
I have reported this criminal (and the criminal counterfeit ring that he belongs to), to the police and legal authorities in Singapore.
Copyright infringement and counterfeiting carries a 10 year jail sentence and $10,000 fine.
