Karimov had essentially called for more criticism in printed material, but only "approved" criticism. In May 2002, the Karimov administration lifted the pre-publication censorship, and fined the chief censor, Ervin Kamilov. The State Inspectorate for the Protection of State Secrets was disbanded. Two days later, the administration proceeded to reinstate further censorship measures. Among topics prohibited in Uzbekistan's publications are official corruption, opposition political parties and Islamic organizations. Radio Liberty lost its broadcast rights. Uzbekistan has one state-run internet server, UZPAK, that blocks prohibited websites. In November 2014, Uzbek students published a letter on the opposition party website, Dunyo Uzbeklari (World of Uzbeks) to protest the use of students as unpaid labour to pick the nation's cotton harvest every year.
