It has registered user accounts, out of which are active (defined as having performed an action on Wikipedia in the last 30 days), and administrators. Since 2013, the Croatian Wikipedia has received attention from international media for promoting a fascist worldview as well as bias against Serbs of Croatia and anti-LGBT propaganda by the means of historical denialism and by negating or diluting the severity of crimes committed by the Ustaše regime. Apart from whitewashing the crimes and vices of World War II-era criminals, the same is done for contemporary Croatian politicians and public figures; this is supported through massive usage of unreliable sources. Throughout 2014, fewer than two dozen editors made more than 100 edits a month; around 150 made more than 5 edits a month. Over 750 articles are ranked as featured (). 2011 reliability analysis In a study by Kubelka and Šoštarić from 2011, the reliability of the Croatian Wikipedia was compared to the Croatian Encyclopedia – the Croatian national encyclopedia. Twenty-four reviewers, experts in specific fields, analyzed a representative selection of articles according to the parameters of informativeness, accuracy of presented information, sufficiency, direction and objectivity. Articles were analyzed in 11 thematic categories: arts and culture; history and biographies; medicine and health; technology and applied science; geography; religion; science; mathematics and logic; philosophy; sport and society; and social sciences. Articles were sorted into categories using machine learning techniques, and feature weight statistics were calculated using tf–idf. A total of 500 articles in 250 pairs were randomly chosen and sorted into categories to serve as representative samples. In both samples, facts were manually enumerated – 3015 from the Croatian Encyclopedia and 3315 from Croatian Wikipedia. Comparison for factual accuracy showed that for every error in the Croatian Encyclopedia, 2.25 errors were found in Croatian Wikipedia. Analysis by individual categories showed that most errors in Croatian Wikipedia were in the philosophy category, where on average two errors in ten articles were found. The only category where the Croatian Encyclopedia had more errors was natural sciences, where the ratio was 1.25:0.75 in favor of Croatian Wikipedia. Of those factual errors, the ratio was 21:12 for major errors, and 34:23 for minor errors. The overall ratio for minor
