I'm not from Bounty Jobs, but I'm very familiar with them. Did you send this question directly to someone there?
I also just wanted to point out that a Recruiter having lots of success there would probably not advertise that publicly so as to avoid increasing the competition on the site further.
Hope you get the answers you want, I've always had great communication with them when I contact them directly!
With a $21,500 dollar fee pending on an interview today via BountyJobs.com I can only hope and pray that he got paid.
If not, well at least I am prepared well in advance.
