Clickcash : World largest adult affiliate network, now offers huge referral bonus for affiliates. Affiliates can earn up to $80 per free sign up. You also earn a 10% "override" on ClickCash sales commissions earned by webmasters you recruit to ClickCash. For example, if you recruit a webmaster to ClickCash, and he earns $1,000 a week in iFriends signup commissions, you collect an extra $100 per week -- 10% -- on top of your own iFriends commissions.
But it doesn't stop there. You also collect 10% overrides on webmaster referral commissions from the webmasters that your webmaster recruits, and the webmasters that those webmasters recruit, and so on and so on, into infinity.
EXAMPLE: Webmaster A refers Webmaster B to ClickCash, Webmaster B in turn refers Webmasters C, D and E. Webmaster A earns a 10% commission on Webmaster B's commissions, and also earns 10% referral commissions on the webmaster commissions of webmasters C, D and E. Webmaster B, meanwhile, earns 10% sales commissions on Webmaster C, D and E's sales. If Webmasters C, D and E recruit their own webmasters, all of the webmasters above the new referrals (A, B, C, D and E in this case) will receive overrides on the "downline" recruits.
