I was just wondering... instead of signing up with a CPA site (like CJ, Maxbounty, Azoogle, etc), Are there any other ways through which I can earn just by referring? When I say referring, I mean person A does nothing more but just sign up in some site X using my referral. FriendFinder.com seems to provide such an offer ($1 per male sign up and $2 for female referrals) but the problem with them is they tend to switch from 'Pay per referral' program to 'Pay per promotion' program if you can not maintain a fair ratio between the free members and paid members you refer to their site. Anyone know of any such sites? Please guide me. Thanks!
