yeah, i hate to say it, but i think it's their right to do it if they want...AS LONG AS THEY PAY YOU your winnings, if u leave, then i think it's their call.....
Now if u had a rollover to meet and they were doing it so you couldnt reach your rollover for a longer period that might be different, but if they choose they don't want your action cuz you're too good, then your option is to take your money and go play elsewhere....
simple math would assume you'll even out, and the book who booted you would be the one missing out and your return to the mean....
but i don't think there is anything "shady" about it
Well they did THAT to me (the bolded part). But hey, it's their loss. My groundbreaking strat of betting on any NFL team in the 2nd half up 14+ at halftime apparently bothered them. Too bad, since it went ice cold in teh second half of the season and they lost out on about $14k that I lost elsewhere.
