language Wikipedia is different from the English one in a number of aspects. Fair use images were forbidden until 2009. Debates have been raised before concerning the fair use policy, all of them failing to have the uploading of such images allowed. Uploading pictures at the Portuguese Wikipedia has even been fully disabled until then. In August 2009, though, a new debate was raised in order for users to approve or deny the creation of a policy of uploading fair use media (named "Uso Restrito de Conteúdo" there, which translates as Restricted Use of Contents). This debate resulted in 142 votes for "yes" against 120 votes for "no", which means the policy was approved and implemented. Like English, Portuguese has regional differences in vocabulary, grammar, and spelling. It is widely accepted that an article written in Brazilian Portuguese should be kept as it is, and the same applies to articles in European Portuguese. However, if one rewrites the article in another variant (provided content was changed, not merely the language), but leaves some words in the former variant, these words should be rewritten in accordance with the new version's variant of the article. In order to hinder SPAM and trolling, completion of a CAPTCHA image was required for all unregistered users to make any edit. It was disabled on January 1, 2014. In 2020, after a community vote that lasted from September 4 to October 4, the Portuguese Wikipedia no longer allows edits from unregistered users (IP addresses). As of 2019, the Portuguese Wikipedia had 316,000 unique categories, 3.57% of them lacking an appropriate page in the category namespace. The average article in this language version has 9 categories, while the ratio of unique categories per article is 0.314. The largest number of articles belong to Arts (16%) and Geography (14%) categories. Articles related to Crime and Events have the highest average quality. Those related to Health are read more often, and articles in the Business category have the highest average author interest. References Lih, Andrew.
