So from my perspective: yes.
Also got some spam and nonsense though. I think the first time I posted it I only got spam and nonsense, the second time I got hired, the third and fourth time I got some interviews and eventually hired.
In one case, I got a very nice email from the CEO, I applied, but I was never told what kind of position I was interviewing for, so it was really tough to tailor my answers and focus.
EDIT: Oh, it looks like a job from a few years back I thought I reached out for was actually them reaching out to me from Who Wants to Be Hired.
So apparently I had good luck after all. :)
For context, it was a security research position.
And that's just the sociopath tech CEOs who're trying to "cast a wide net" wrt recruiting (i.e., lying in their email responses to you about how they "saw" your post and thought you might be "a good fit"). I still also get straight up junkmail sent to a single-use email address that I once posted in a "Who wants to be hired?" thread. Take appropriate precautions.
