Wikipedia:Ghostwriting

Ghostwriting on Wikipedia involves organizations and individuals bypassing the conflict-of-interest guideline by supplying approved drafts of articles about themselves. They may write the material in-house or hire external PR professionals. Volunteer editors copy the material into the encyclopaedia as though it had been written independently.

Wikipedia has no mechanism for signalling to its readers that an article has been ghostwritten. The practice is not against Wikipedia's rules, but is controversial. Sections of the community regard it as unethical. Others defend the practice, arguing that what matters is content, not authorship.

Editors who add this material to articles are expected to check it for balance, accuracy and appropriate sourcing, but because of scarce volunteer time, a lack of expertise, and a desire on the part of editors to be helpful, company-approved drafts may be carried over into articles with few checks, if any.
