Awadewit, Dispatches: Let's get serious about plagiarism (2009)
“ A reader may have cause for concern if a section of an article seems to have been written "too well". Much writing on Wikipedia is not at the level of professional publications. Therefore, when readers suddenly come across professional-level writing on Wikipedia, with no spelling or grammatical errors, they may want to investigate further. If the article has been extensively copy-edited, such as in undergoing the featured articles process, such polish is in itself less of a red flag, though even extensive copy-editing does not guarantee the absence of plagiarism. ”
