Latest season: The Child Cancer Scam. Your child is critically ill. It’s the worst news you can get. But to make the situation even more awful, you struggle to afford the care they need. So when someone tells you a foreign sponsor can help raise the money, you’ll do anything. You make a video: your child begs for help from strangers online. But it comes to nothing. You wait and wait for the cash that was donated. It never comes, and all the while your child is fighting for their life.
