These guys in England love to play with the scammers. Send your letter into them.

I just noticed that the site I posted in comment #61, does the same. They must have lots of fun! They say:
"If you have received a scam letter similar to the ones in the first few letters it would be very much appreciated if you would email me the original letter with their email address so I can take care of them! Thanks!"
