I used to spam their email addresses when I got those. Then it got to a stage where such emails were coming all the time, so I simply got a new hotmail account.
I remember reading a funny book by Danny Wallace, entitled "Yes Man". It was turned into a film starring Jim Carey, but it was not as good as the book IMO. In the book he goes to Holland after responding to one of these types of emails in order to help the person emailing him out. The book itself is about him going through a period where he says "Yes" to everything, in order to change his life and make it less boring and inactive. I enjoyed reading his experiences.
