earned me money? you do understand that i am just starting and all i have made is losses and most especially from having an address with large referral. A referral fee is supposed to be a one time claim on everyone the referrer brings, not continuous. I can't work with continuous. Still going to block the address after sometime because i will need to increase my referral fee soon enough. You want more referral satoshi? provide another address and bring in new faces. That's how it's supposed to be. I can't be indebted to you forever.
You have basically two options:
1. A referral commission in percent of what the referral earned. If you earn eg 3.90BTC from them through ads and pay out a 10% commission of 0.39BTC, you still keep 3.51BTC. Then there is abosutely no reason to cap the commission, unless you want to piss of your partners by looking greedy.
2. A "bounty" program where you pay for every referral who signed up under a user. If you do that blindly just based on sign-up numbers, well no surprise that it gets abused. It's easy to create hundreds of fake accounts and pile up the bounties on the main account. Tie that to a requirement, eg "bounty is only paid after the referral earned amount X".
