Why do you care? Are they forcing you to wager your money? Did they put a gun on your head? No. Whoever is falling for that scam and wagers more that he could afford to lose deserves to lose that money.
I bet most of the high rollers you see in the casino scoreboards are fakes. (maybe all of them)
This is just not right. You can say the same to every drug addict. "These drug addicts deserve to be addicted, because they tried it out". Why is this not corrrect? Every person can be a gambler if she or he is in a bad shape for a couple of reasons. This kind of (stupid) marketing cann of course trigger very bad behaviour.
