Yes, but a tiny percentage. A lot of spam. (_A lot of spam._) Tons of recruiting services. 80% of people obviously didn't read the post.

That said, I have hired a few amazing people, including some great technical leaders, that would have cost 15-20% salary to use a recruiter to find & snipe (this was before I had internal recruiters to help).

I use a separate email alias for it, and have a few canned responses (1/ you didn't read the job post 2/ I said we cannot do visas or major relocations, but you're in Greenland 3/ too junior, but please keep an eye on future posts) to keep things efficient.
