Here are 2 rules from an agency contract than will be found in ALL agency contracts you will have agreed too. I have deliberately blocked out the agency name but the rules are fairly standard across the board.

13. ******* reserves the right to close a Member's Betting Account and refund the balance of his/her account without further explanation.

29. ******** reserves the right in its sole discretion to decline, or to limit, any wager a Member may wish to place without further explanation. ********* is not required to state or provide any reason for refusing or declining to accept any bets.
