The Portuguese language Wikipedia is different from the English one in a number of aspects. • Until 2009,
fair use was not allowed on Portuguese Wikipedia. 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 was even 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. Nowadays, fair use files are labeled as "Conteúdo restrito", meaning restricted content. • 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
spamming and trolling, completion of a
CAPTCHA image was required for all unregistered users to make any edit. It was disabled on 1 January 2014. • Since 2020, after a
community vote that lasted from 4 September to 4 October, 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 nine 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. In April 2022, the European Union's
East StratCom Task Force published its findings that four pro-Russian disinformation outlets (
SouthFront,
NewsFront, InfoRos and
Strategic Culture Foundation) were referenced in 45 articles of the Portuguese Wikipedia. This made it the Wikipedia edition that was the fourth most-affected by such disinformation, after the
Russian,
Arabic and
Spanish Wikipedias. The Task Force wrote: == Notes ==
