"Since Sheldon Adelson is lobbying against Internet poker, I will no longer play at The Venetian poker room," a player wrote on the TwoPlusTwo.com message board. "I suggest if you care about the issue, that you also boycott the room."
On Thursday, Poker Players Alliance spokesman Richard Muny told Internet poker proponents via QuadJacks.com radio to express their opposition to Adelson's stance with Twitter tweets to The Venetian.
Zach Tracy, who writes for Pokerfuse.com, encouraged players to frequent casinos owned by operators that support poker legalization.
QuadJacks radio host Marco Valerio said poker players are angry and frustrated.
"You are dealing with a very sensitive community at this point," Valerio said. "Recent advancements provided some encouragement, but now it's devastation again."
