Unfortunately, it's not foolproof. During the ~20 years that my predecessor in my current job worked in it, it gradually evolved from being primarily a hardware position with a little software development to primarily a software position with a little hardware building. My moderate expertise with electronic hardware helped get me the job, but then I basically never had to use it in the ~15 years I've been here. I still get multiple emails from Electronic Design daily. No amount of attempting to unsubscribe stops them. I've blocked multiple sending email addresses; they rotate them fairly frequently. It's possible I could report them for this (I haven't researched it), but since I think my spam filter has missed maybe 1-2 emails in all that time, it tends not to be worth it.
