Zhemao hoaxes
The Zhemao hoaxes were over 200 interconnected Wikipedia articles about falsified aspects of medieval Russian history written from 2012 to 2022 by Zhemao (Chinese: 折毛; pinyin: Zhémáo), a pseudonymous editor of the Chinese Wikipedia. The articles were fictive embellishments on real entities; Zhemao used machine translation to understand Russian-language sources and invented elaborate detail to fill gaps in the translation.
