I don't have a problem with this sort of sting, as it catches morons who are defrauding people out of their hard-earned money, which could include any of us. Where I have a problem with stings is when they're designed to protect people from themselves, such as prostitution or drug stings. Not that I think either of those things are good ideas, but I think people who are free should have a right to be stupid as long as it has a relatively minimal effect on others.
