Odd Job

In looking for a new job, I have signed up for every known Job Board out there (Monster, Dice, Careerbuilder, etc...). Most of the responses I get are scams, jokes and in no way follow any of the job type / category settings I have setup and have listed.
The other day I received an email telling me that they noticed my resume and thought I would be a perfect match. This is pretty much the common email response I get before they dump a horrible position description in my lap.
But this one was different. This one made me think: "Is this even legal???"
