Good marketing skills must be possessed by someone who wants to become an affiliate of a site. And not many people have that ability. Some time ago, I followed an influencer on his social media, he was a person who rose because of some of his joke content. After a while I followed him, and when I saw the stories he made on his social media, I found out that he was also an influencer promoting a gambling site, and I noticed he was getting a lot of new users. One of the things he did was that when someone won on the site he was promoting he made a new user win through his story too, well from there I saw that it was a form of strategy he did by taking advantage of someone's victory, indirectly some people might be more interested and register on the references he spread.
Yes, I have seen some of the influencers who also promote their own referral code and at the same time give new users who register on the casino using their affiliate code some bonuses and this has really promoted them and at the same time earn them a huge commission.
But then we must know that an affiliate program comes with a lot of tasks because sometimes for you to be able to earn a good amount in your affiliate commission you need to have wagered and also those who registered with your referral code need to have wagered a lot during the space of time.
I guess op thinks claiming referral bonuses are impossible but the truth is that they are actually possible to claim but it all depends in how much gamblers you know and how much community of people you have and I've also seen some online commendy skits where comedians display their referral links and codes and always make adverts with them and I believe they should getting some engagements from that too and you should know that It must have taken a while lot of effort to grow such pages
