resume cops?

This article discusses a product that can supposedly tell if a person's resume has been altered. "They can even tell if the cover letter or resume has been recycled from a previous job hunt."

Is this a joke? Or maybe a test to see how many people read the paper w/o buying it, because it would be sure to generate a lot of letters? It was on the first page of the business section of the Atlanta Journal-Constitution on May 21, 2006; it would have been more appropriate to April 1.
I won't discuss the stupidity of this idea, because it's obvious to anybody who has looked for a job. I would just like to say that I would like a list of any companies who do this, because I wouldn't want to work for anybody that stupid.
