In my experience, these places don't actually make any money, so fear not. I did some database consulting work for a company that was in a similar business a few years back. They wound up shutting down after about six weeks because no one bothered paying them. Out of more than $12 million in demands, they received less than $4,000 after sending their first batch. That was when they decided to shut down. I suspect something similar will happen with these guys and anyone that follows them.
