These guys scam the scammers AND HAVE FUN DOING IT.
The letter Archive section has details of how they do it. I have only read a little so far because there is a lot to read as they string em along.
Especially "The tale of the Painted Breast" which is very long to read, but this guy cons the scammer into sending HIM money..lol
"The mark of a Moron" he tricks the guy into getting a tattoo. :lol:
