My wife worked in one such company several years ago. The interesting thing is that while hiring her, she couldn't even anticipate that the company was a scam. The company described itself as a certified technical support service. They showed her such a rosy picture of the work they did. It was only after a couple of weeks, when they had explained the processes, that she realized it was a scam.
She left soon thereafter. By the way, they were ready to pay whatever she asked for (up to a reasonable limit of course). The tragedy is that people in countries like India need to survive, and values take the back seat.
Two more such companies offered her the same kind of job but she declined.
