Jakarta, Indonesia (CNN) -- The former editor of Indonesia's now-defunct Playboy magazine has been sent to prison for two years.
"They can lock me up, but my spirit and ideas will remain free," Erwin Arnada posted on the microblogging site Twitter.
He was sent to prison on Saturday for distributing indecent pictures and profiting from them.
Arnada's lawyer said on Monday that they will seek a judicial review.
"We want to review this decision," Todung Mulya Lubis said. "The magazine did not contain any pornographic material [and] was in line with the press code of ethics."
The Indonesian magazine did not show nudity, unlike its international counterpart, but it caused a stir when it launched in 2006.
A small but vocal hard-line group called the Islamic Defenders Front pushed for legal proceedings against Arnada and vandalized the Playboy office in Jakarta.
"I don't know why Playboy is targeted when other magazines have more revealing pictures," Lubis said. "The country is supposed to protect the journalist under the press law, not prosecute them. This is why this decision actually sets a bad precedent for the freedom of expression."
Indonesia is the world's most populous Muslim country, but most Indonesian Muslims are moderates.
