One site using Google Maps has received a polite message to remove its contents from Google. A thread on Google Blogoscoped covers this. I remember visiting this Wallpaper site recently, now it just contains the removal message Google sent them.

This is the first time I've heard that Google have requested the removal of such a site using a Google map hack. There are many more and one even got a mention on Google's official blog - will they all be heading the same way?
