It's not debatable, they understand already that gambling is a risky game so they need to accept whatever the outcome.
I have referrals and I believe they are losing but I have not received any messages telling that I was blame because they lose in gambling. Maybe the right person to be blame is themselves.
You are right! They have their own decision to make, they are responsible to know the risk of gambling. Inviting friends to refer has a hard part also, you should have a good charm of encouragement; you need to help them too on how to earn.
It is true that having referrals on a gambling site really earns you a passive income but as you said it is really hard to get good and active gambling referrals, even if the referrals don't blame you but mostly they stop doing something they did not started by their own but they were referred to it.
referrals need to constantly change. some no longer profitable after only a month after their involvement. I can not call it a passive income. To get a good referral is necessary to work hard
Referrals are just for a short term income and I don't think it can be called a passive income either because having a single referral is too hard to get. And it is needed to be taken care very well, I've been doing this for a paid to click site and I tried also to gambling sites but it is kinda a hard work for me so I can't say that gambling referrals will give you a passive income.
No passive income from referrals for sure. Hard to get them, and 70% of them wouldn't click or do the task to give you comission. Maybe some site owners can get a lot of referrals to give comission for them, but the mass can't get it.
I understand the difficulty you have to bring referrals with you, I have the same difficulty, I don't try to get them anymore, now I just join sites which I can make good profit alone, by myself.
