The same nothing that does not stop the companies actually seeking their own employees also does not stop 300 recruiters from copying their posted text, stripping out the original company-identifying information, and re-posting.<p>The noise added to the signal does make it significantly more difficult.<p>So rather than searching a central repository of job ads for opportunities specifically relevant to you, you have to visit individual company websites, find the &quot;careers&quot; or &quot;jobs&quot; section, and look for leads in a thousand different places.<p>I consider a no-recruiters policy to be absolutely essential for a job advertisements boards now.  Everywhere else, you have to filter out key phrases like &quot;recruiting&quot;, &quot;our client&quot;, or &quot;resume in Word format&quot; just to find anything useful.
