the German Wikipedia": on 14 September 2005, 253 pages had been in a fully protected state (only editable by admins) for more than two weeks. This was the highest total of any of the Wikipedias, with the second-highest being 166 pages in the Japanese Wikipedia and 138 in the English Wikipedia. , the German Wikipedia still had the highest percentage of semi-protected articles (articles not editable by unregistered or recently registered users)—0.281%—among the ten largest Wikipedias, but in terms of the fraction of fully protected articles (0.0261%) it ranked fourth, behind the Japanese, Portuguese and English Wikipedias. Handling of vandalism and other abuse is less structured: vandals are sometimes blocked on their first edit and without warning if their edit clearly shows lack of interest for actual encyclopaedic work. This is especially true if added text includes unlawful statements, such as holocaust denial. Similarly, the Checkuser function is rarely used to confirm usage of multiple accounts by the same person, as suspicious accounts are often blocked on sight. Articles on indisputably notable subjects may be deleted if they are deemed too short. While the requirements for minimal articles (called stubs) are equivalent, the German and the English Wikipedia differ greatly in the way they are put into practice. On 28 December 2005, it was decided to eliminate the Category "stub" (and the corresponding template identifying articles as stubs) from the German Wikipedia. Users do not have to create an account in order to start a new article. Unlike the Cebuano, Polish, Dutch, Italian, Swedish or many other Wikipedias, the German one does not contain large collections of bot-generated geographical stubs or similar articles. The German Wikipedia version did not have an Arbitration Committee until May 2007. Currently, German Wikipedia's Arbitration Committee plays only a minor role in Wikipedia politics. Categories are singular and are not differentiated for gender. Categories are usually introduced only for a minimum of ten entries and are not always subdivided even for larger numbers of items, so that current categories often describe only one property (e.g., nationality). Other categories are subdivided, but differently from in the English Wikipedia. For example, "chemists" are subdivided by century, not by nationality. University professors, on the other hand, will usually be categorized according to where they teach. The equivalent to the English Wikipedia's featured articles and good articles are exzellente Artikel (excellent articles) and lesenswerte Artikel (good articles; literally: articles
