It likely depends on how big your online footprint is. I've been on the Internet publicly since 1989 and hence you can find me all over. That also means recruiters do. I have no problems with the ones who are good at their jobs, but about half are below average, working on commission, and their tactics are the same as spammers (spread yourself indiscriminately far and wide). Many are downright scammers such as taking resumes off the net and then pretending to represent those people, or scraping job postings off websites and then pretending to represent those companies.
At the top of my resume I put a "note to recruiters" that makes it clear what I am good for. It is very clear then which recruiters have made even that miniscule effort, versus just started spamming right away.
I'd say I see about one good recruiter for every 20 spammers. And that is what is bothering. Even worse the lack of response or saying no doesn't deter the spammers so you have to do something about it. I made a blocklist in the end.
