There's something I understand about affiliate marketing or referral program is you don't have to stress yourself that much, all you needs to do is just share your codes in a well known telegram or twitter. There are some referrals which I won't advise you to join or even go about such as those telegram from bounty's they are much stress at last will end wasting your time with just a common bot that will keep telling you to ref more 5 person to be able claim your rewards.
Well, it's not really as easy as you are describing it, I believe gaining referrals require a lot of work at the beginning, and the work must be done in the right manner or it will only waste your time and you will gain nothing at all. You also need to make sure that the referrals that sign up under you are active ones and aren't just those who create accounts and then abandon them.
It's true that once you got a decent amount of referrals, you won't need to stress yourself out after that, but the initial work is pretty stressful and time-consuming. Also, gone are the days when sharing the link used to get you referrals, now a days, you need to use different techniques to achieve that.
