There are a lot of myths in the business world. One is that recruiters exist to screen you out, and hurt your job search.
With this in mind, ponder HR Capitalist's post, What Would an HR Capitalist Do? She Would Not Talk About Fight Club..., and particularly the second to last paragraph.
So, the next time you think some crusty recruiter is standing in your way of your job, take a day or two, or maybe a week and think a bit more about all that this person has seen in their job, then figure out how you can help them. When the real deal shows up at the door of an HR Pro, they remember, just as they remember the really bad stuff.
