It seems since 2009, Harrah's (now Caesars) has a policy of banning identified blackjack card counters from all its properties, including the WSOP. In a Nevada Supreme Court case in 2009, a card counter fought this harsh measure that apparently exists today with the Joseph Stiers incident. Read page 18 of this NV Supreme Court case

A card counter must never produce a Caesars Total Rewards players card or a drivers license to the pit when playing blackjack. If one is identified as a card counter, then it's adios to playing the WSOP along with a banning from all Caesars properties
