Basic Trope: A fight between two or more wiki editors, where one troper will initiate a change, another will restore and/or override it, and so on...
Straight: Two tropers can't agree on whether or not a specific trope example applies, and start changes back and forth.
Factions of tropers can't agree on whether or not a specific trope example applies, and start a holy war of edit carnage.
One of the people involved in the Edit War is an admin, who promptly has the entire article Zapped after somebody posts something s/he does not agree with.
Downplayed: Two tropers can't agree on the spelling of a name, but otherwise leave an example alone.
The information is off enough to be counted as wrong, but the deleting troper in question forgot what the actual correct information was. He is only removing until that editor goes away or somebody who knows the detail sees the page.
The poster of the information is correct, but the editor only saw another part of the wiki with wrong information relating to the current item. The poster hopes that somebody who knew the source would come along and validate the correct information.
