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)
I agree, when it comes to playing it's up to us where, when, and how much are we going to spend or wager, I don't see how these high rollers perform all I care is how I will play and how much I am going to wage, I already know that there is a lot of fakes advertising but I choose to ignore as long as I only play money I can afford to lose.
