The privacy-invading insider who leaked the infamous nude photos of Prince Harry playing strip billiards is persona non grata in Vegas, according a new Sin City tourism campaign.

"For Shame! To those who traded in their pledge to their Las Vegas brethren, WE DEPLORE YOU," reads the copy of a new ad campaign launched by the Las Vegas Convention and Visitors Authority in the wake of cellphone pic scandal.

It continues: "We are asking for a shun on those exploiters of Prince Harry. We shall boycott partying with (whoever exploited Harry). No bottle service. No bikini clad girls."

The LVCVA is asking all "defenders of what happens in Vegas staying in its rightful place" to sign a pledge promising to report all those "who violate the code."

"Las Vegas is about adult freedom," a spokeswoman for the board told USA Today. "It's important for friends to know what activities can be shared publicly and what activities are protected by the code."

Meanwhile, Us Weekly is reporting that more royal pain may be on the way for Harry.

British publicist Max Clifford told the gossip mag he'd been approached "by two American girls" claiming to have in their possession more photos from the prince's buff Bacchanalia. Clifford says he turned them down, but insists there's more still to come.

"It could get worse," he said.
