My sister, a journalist, once replied to one of these e-mails and started a dialogue with them. As the conversation went back and forth, she made it increasingly clear that she was a priestess in a White Supremacist church (the Church of White Fire, I recall
) They didn't seem to notice. She strung them along for a while but then got a bit bored. I think she was made to take the website down with the conversation on it as some do-gooder complained, but it was very funny at the time...
