You may want to look closer. Many are complete scumbags. Here are some things the unscrupulous ones do: * Pretend to have positions they don't, so they can claim to have thousands of candidates on their rolls * Edit resumes/CVs they submit to add fictitious information * Scrape positions from companies and pretend they are front ending those positions, even though they have no relationship to the company, and the job spec says "no recruiters" or similar. * Make no effort to match candidates and positions ie they aren't offering actual work, they are lying about what they offer, and they do not have the companies or candidates best interests at heart. It is quite hard to tell the difference between a competent recruiter and a scumbag. One simple thing to do is Google parts of email they send you.
