This shows how people are cheated by a group of (white) Russians. Well worth a look. Sportsbet.io is also involved into this.
Not surprised to see this attacks on casino since we know the competition is so high and other who doesn't want to fight fairly create this kind of bad publicity just to create bad impression to the attacked casino. But I'm skeptical about this and I will believe only on the claims which have valid proof since taking those words without proof and just pure hearsay will not result good here.
