The semi-official Tasnim news agency said the network was involved in producing and publishing pornographic pictures and spreading “depravity” in society.
The reports said the 11 people detained were “key elements” of the network, which was active in the southeastern province of Sistan-Baluchistan.
The government news agency IRNA reported that 50 people were apprehended and released after receiving “guidance.”
Three underground studios used by the network were shut down, the reports said.
In May, authorities announced an operation targeting modeling posts on Instagram.
Authorities said several people had been arrested for posting pictures of women without their compulsory hijab -- a crime in Iran.
