Not necessarily. It is possible stale2002 gets emails from recruiters simply because he's on a list somewhere. Recruiters are not known for investigating people thoroughly before bulk sending of emails.
I had done some SharePoint front end design when I was on an editorial team and we needed some features in our SharePoint site in 2008, but had to take any mention of SharePoint out of my resume because I got too many contacts from recruiters looking for a SharePoint architect.
I'm also a Zend Certified Engineer in PHP (don't hate). I'd never worked with Zend Framework, but would get very regular recruiter contacts because they didn't know the difference between "Zend" (a company) and "Zend Framework" (an MVC framework that was just one of their products).
