A young man in Karachi was excited to land a high-paying job offer but was told he needed to pay for mandatory job training first. After paying for the course, the "company" disappeared, leaving him without the job or his money.
It was not Pakistan but I had almost got these scams in LinkedIn by being told the recruiters had very great opportunities but I needed to pay 500 USD for registration fee and they required with Bitcoin so I didn’t process it with them.
