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)
Lol, you mean gambling with Russian roulette?
I'm not in favor of it but if people are going to do that then they'll put all their life's earnings on the table when on 1v1 with another, the winner gets to live and take the money of the other.
In any case, it's immoral and should be prohibited.
Lot's of people find gambling itself immoral but people gamble anyway.
If you think showing fake high stake players is unethical, then most people that gamble are also being tricked because most of them think gambling as a job. The players should lose in the long run because that's the only way for the casino/house to keep doing their business.
