here a small opinion by my thinking ,
it is obvious we will lose 90% of the time in gambling,
so, think an influencer referred anyone, who is very new to gambling and deposited some money in greed of the welcome bonus provided by casino, then he knew, to claim this welcome bonus he need to wager the required amount to claim the bonus, while wagering he won in starting and he was feeling very happy first day of gambling, and now comes, second day he logged into the site to wager more to claim bonus and after playing some time he lost some money and he started doubling the bet amount to recover his losses, and by doubling bets many times he busted his whole account and made balance=0, and if he is smart enough(many of new are very smart they deposit second time to claim bonus and recover their losses but, not that much smart there eyes become blind by seeing quick profits and losses they do not able to revise that 90% of the time i will lose at this gambling game) and he is smart and deposited second time by deciding that, i will wager the left required amount and claim the bonus then never ever will gamble, but this time also he losed all, then he is depressed and thinking in different way (thinking that i will deposit one more time, when i first tried i doubled my account so this time i will deposit something big amount then previous amount) then this cycle repeats many times , and after all he fall into depression may sometimes many people sell their house and cars and live very bad life and their family also suffer for his/their mistake,
You make a lot of bad points quite frankly. You talk about promoters not telling you the terms and conditions, yet they are plainly found on every single gambling span and can cover many pages of content. It is the responsibility of anyone who is spending money to read them and understand what they're doing, they often agree to this right there on the registration page but only complain when they don't beat the house. You also ignore the fact that everyone who takes part in casinos or gambling in general, thinks they are more clever than these huge companies and that they will somehow get a magical shortcut to massive wealth, that too is the definition of greedy.
