as I said earlier if someone spreads their referrals they only think about profit or income from their referrals, those who spread scam casino referrals will not care about any risks and don't care if people are deceived from their referrals the most important thing they think about is profit and income without see too many people who are deceived by referrals that are spread even though the casino is deceiving
They won't be able to get the money if they only think about money but they have to think about the people they have invited to join. Usually, people will be interested in joining if there is attractive compensation, so they will voluntarily join and deposit their money. I've heard that some people spread their referral links on social media and offer that people who join them will be given some money, which makes people want to join. Maybe it's a strategy that some people out there continue to attract new members.
If they have been successful with that method, they only need to keep an eye on the amount of the bonus, which might immediately increase sharply because they have shared some of the profits with the new people. They may successfully spread the referral link if they pay attention to this.
