Make Money Referring Affiliates to Clickbank

Is it possible to make money referring affiliates to Clickbank?

I was looking to see if Clickbank has an affiliate program of it's own (refer an affiliate make 5% of their sales etc.... sort of thing) and could only find the publisher version (you can make money when someone publishes a product after visiting Clickbank from one of your links).

I did find a link like this on another site, but haven't been able to find anything on the Clickbank site.

I guess Clickbank don't use their own program to generate more affiliates!
