Keeping a job board free of recruiters is quite hard. That's why for http://jobs.usethesource.com/ I made posting rights be based on your Hacker News karma. Be part of this community and you can post jobs on UseTheSource.
Not so difficult when you used to be one yourself! Also, a blanket ban on recruiters is counter-productive as we have established that there clearly are a tiny percentage of decent recruiters, those are the ones we are happy to allow access to.
