Without a doubt this is a problem for those which try to earn money by the use of referrals, even if they can refer a lot of gamblers to many different casinos, if at least one of them is scammed or even believes this was the case this is enough to ruin the reputation of that person, even if they are doing the best they can to only send those gamblers to reputable casinos, so the more I think about it the less it makes sense to engage in this activity in which you can lose your reputation over something that was not really your fault.
when it comes to "the important thing is to make money, it doesn't matter if the casino is a scam or not" it is very difficult to give advice. because those who only think about making money they don't care about everything he thinks only of how to attract more gamblers into the casino using his referrals.
it is very sad to see someone who is willing to sacrifice reputation for earning money without thinking about the fate of others who walk into a scam casino and lose some of the money they have.
