Did it have any effect whatsoever on the flow of spam?
(I was nominally responsible for a Clearcase installation for six months in 2001. I mentioned it on my CV in 2002. I still get the occasional ping from those last, last few Clearcase shops, desperate for someone who will admit to ever having touched it.)
If you've worked with some technology or product, but don't ever want to work with it again, don't mention it in your resume.
I mentioned doing some ColdFusion work because, well, that's what I did as part of a previous job, but when I started looking for a new job, I quickly found I wanted to take that out.
Of course, if word gets out you're a software developer looking for work, there are a whole slew of recruiters that will spam you for anything that even remotely involves computers. It's been 2-1/2 years since I was looking for work and I still get a couple e-mails a week spamming for jobs like a Linux Admin in Detroit or a Data Analyst in St. Louis (I live in Virginia and never had any intention of moving).
The recruiters seem to be catching my drift in a rather oblique way, in that just since yesterday, they've been sending me inquiries about jobs in Portland, Maine.
