This has always been true of physical casinos as well. If you win over time, you'll be 'uninvited' - as demonstrated by how quickly casinos will ban anyone they think is card counting in blackjack (which isn't illegal or against to rules). I guess I'm surprised anyone is surprised that casinos do this and always have. There has never been anything "fair" about a casino's relationship with players. Your only role in the relationship is to, on average over the long run, lose money. Their role is to take your money. A "sharp" player is anyone who consistently plays in a way that, on average over the long run, makes money, breaks even or minimizes your losses below the expected rate of return in the casino's financial model. Any player who is not a sharp, is a 'valued customer' (aka 'playing like a consistently predictable loser'). Casinos have always been adept at spotting any players who behave in ways more like a sharp than a valued customer.
