...the Everest of scam baiting is to con the conmen and get the fraudsters to part with cold hard cash. Only a few have managed this. One, writing under the moniker Bart Simpson, managed it by telling his Nigerian criminal target that he was being courted by another offer from West Africa. Bart said that this other correspondent had sent him $5 in a greeting card and he would sever his relationship unless the fraudster did the same thing.
BWAHAHAHA! Priceless. You have to click thru on that link and read the email exchange. More intricate and brutal is the solution of the true hacker.
Particularly vindictive anti-spammers will also send "supporting documents" to the fraudsters. When downloaded, these are found to contain not helpful bank details but particularly vicious viruses that cripple the criminal's computers.
One scam baiter managed to get her target to fall for this seven times before he got the message. Read how here. This means he either saw seven expensive PCs reduced to smoking rubble or spent an awful lot of money on repairs. It's hard to feel much sympathy for him.
Am I a bad person for celebrating the pain and hardship of spam scammers? I don't care.
