I first noticed www.worldnetdaily.com and www.drudgereport.com doing this to yahoo news. Both of these sites are high volume sites that make their money by linking to stories. By adding '&printer=1" to links, about 90% of yahoo's ads are removed. This means that yahoo serves the stories, but doesn't get paid.
I'd be pretty easy to redirect to the original story with ads if the referer is anything besides the original. Here's a perl thing that should check for bad referers if(($ENV{HTTP_REFERER} ne '')&&(!($ENV{HTTP_REFERER} =~ /^http:\/\/($host).*/))) where $host is the domain of your site. -- xm () while1 net (http://while1.net/)
