See, if everyone played with them, and cost them more than they gained by scamming, then at some point they'll figure out it's not worth the effort.

Maybe off topic but fun. I like to make them think I got it and cashed it but decided not to send them the animal or the money. We all know they never planned on having the animal picked up. I have had good luck getting a good bit of information by doing this. I even had one guy call me from a New Jersey land line that matched an ip address. I took it all to the local post master and never heard from them again.
May as well waste there time and counterfeiting skills. Some are quiet good. They usually send it overnight costing them money as well. Send them to Walmart or western union to retrieve their money just too find out you accidentally gave them the wrong information.
