"Crazy Rich" is a coveted term, no matter what, the important thing is to get money, to know. The method can be an endorser, influencer or affiliator, some are even more "crazy", so buzzer!.
First what goods are sold, what services are sold? If the goods and or services are like gambling equipment and their implementation, yes obviously already, leave it, there is still a lot of money elsewhere.
How about endorsers, influencers, and affiliates? but the goods and services it sells are okay, there are even halal fatwas, for example for Sharia banking, Sharia Stocks etc.
However, everything has rules, therefore ask, confirm, validate, check and check with experts, especially experts in the field of Muamalah Maliyah.
Pay attention to what contract is used, how to get along and the conditions, is it fulfilled? In Muamalah endorsers or whatever the name can use several contract options, for example:
Akad Ijarah: Like a salesman, his services to sell an item will be given wages.
Akad Samsarah: A broker gets his wages from one party, whether seller or buyer, with a percentage or price difference, to sell goods, or find goods.
Akad Jualah : Wages will be given if the target has been achieved, if the achievement has been met.
Of the several choices of the contract (akad), the important thing then is morals, you can't exaggerate or overdo it in selling an item, to be honest, if there are shortcomings then just say it.
Selling, directing, let alone influencing blindly, without thinking about halal and haram, only thinking about money, is an act that injures humanity, is an act of tyranny, sacrificing freedom as a human being, even denying being a servant of Allah Azza wa Jalla, preferring to be a servant of money.
"Woe to the servant of the dinar, woe to the servant of the dirham, woe to the servant of khamisah and khamilah (a kind of garment made of wool / silk). If given he is happy, but if he is not given he is angry" (Narrated by Bukhari)
Always be grateful, stay captive, stay qanaah, keep trying. Focus on the intent, not on the naming.
Wallahu a'lam bishawab
