Two issues would help tremendously:
1. Consistently pay US players in a timely manner, such that withdrawals take the same amount of time as non-US players.
2. Pay the hundreds? of players whose winnings were confiscated recently, as described at http://www.casinomeister.com/forums/casino-complaints-non-bonus-issues/16977-locked-account-royal-vegas-vegas-towers.html
. It should be very simple. If a player follows your T&C and does not commit fraud, you pay him. If you don’t like the style of play for whatever reason, then you can ban him after having paid winnings and/or change your T&C to prevent that style of play.
