Fans insist he did nothing wrong, making the tapes in the privacy of his own home. But Islamic hard-liners warned that his actions had contributed to the country’s moral decline.

The 29-year-old singer ― who said the videos were stolen and posted online without his knowledge ― was the first celebrity to be found guilty of violating the country’s strict anti-pornography law that went into effect in 2008.

Presiding Judge Singgih Budi Prakoso said the star made the videos with two celebrity girlfriends and did nothing to prevent their wide distribution.

He sentenced him to three years in jail ― well short of the maximum 12, angering hundreds of protesters who gathered outside ― and fined him $25,000.

“As a public figure, the defendant should be aware that fans might imitate his behavior,” Prakoso said, adding that Ariel, lead singer of the group, Peterpan, also showed no remorse.

Indonesia, a secular country of 237 million people, has more Muslims than any other country in the world. Though most are moderate, a small extremist fringe has become more vocal in recent years.

They have pushed through controversial laws ― like the anti-porn bill ― and attacked anything they perceive as blasphemous, from transvestites and bars to ‘deviant’ religious sects.
