Uncyclopedia, Memory Alpha, DC and Marvel Database, and probably more, were independent websites purchased by Wikia. As such, they've maintained some special privileges. I think part of Uncyc split off again anyway.

I know of Minecraft's Wikia and Gamepedia wikis, but can't think of any independent wikis. There have been several big forks, which now strive either independently or at another farm.
