Istanbul police have arrested 50 contributors to Turkey’s largest user-generated dictionary. The “Sour Dictionary” (Eksi Sozluk) site offers satirical definitions of a number of common words and has been running for around 12 years. The anonymous authors, who were identified through their IP addresses, have been charged with “insulting religion” following a complaint over a discussion about the prophet Muhammed. The site’s administrators have faced criticism for agreeing to hand over authors’ IP addresses to the police.
