Worse than that, motivated editors often color their pet pages with specific nuance and context, and no casual editor has a hope of winning an edit war against such opposition.

My favorite example of this is the debate between a faction that believes Lithobates is the proper genus of a certain set of frogs, and another faction that believes the correct genus is Rana. The Lithobates side is essentially one person along with his sock and/or meat puppets, so in the end, after many rounds of moderation, most of the species in question are listed under both genuses.
