Help:Citation needed
From IntactWiki
Often, a {{Citation needed}} tag is added because the information is known (or believed) to be true, but needs to be verified with a proper citation. Otherwise, said information would be removed instead of simply adding a {{Citation needed}} tag.
To ensure that all Wiki content is verifiable, anyone may question an uncited claim by inserting a {{Citation needed}} tag. If someone tagged your contributions with "Citation needed" and you disagree, discuss the matter on the article's discussion page.
