>Surely there is ground for "the mistake is yours, the money is gone" approach not really. Pretty much every jurisdiction has laws regarding transaction errors, you can't just go blow a couple of millions just because someone made faulty transaction. If you notice random amounts of money in your account, don't go out and spend it.
