I'm not the first to jump up for more regulation, and for something like this I'll be the first to admit that it's my responsibility to read the fine print, but this is very deceptive. A line needs to be drawn somewhere and customers need to be protected once it is crossed. I will add that to protect yourself from these and other payment related issues online, have a special low balance card or get one-time card numbers. I know most savvy members on HN already do this but just mentioning it in case.
