We did it in the same way like with CCBill.
Every EpochStats id (s=) was checked, programs identified and listed at
SignbucksDaily (click EpochStats on the grey ribbon to get them all).
Some sites don't have 'Webmasters' link, so it took some effort to determine their program and join it. At Signbucks Daily you are provided with direct ES link for webmasters. And many programs aren't configured right to be promoted by affiliates (and it took to determine that), so it wasn't easy job.
!!!There's very important thing about ES programs i've discovered. Webmasters are credited only if join page link is like this

are not ok
There's a lot of gay stuff on epoch and pps programs ($20-25). I've also found the most awesome shemale erotic paysite (i'm not a fan of that niche, but paysite is truly amazing) and one very weird thing.
Good luck everyone
