Really? I was under the impression that wikis generally are under a "Yeah everything here's free to use, whatever" license. And if that's not the case, then what's the legal basis for the maintainers of one wiki to just leave and copy everything over to another one?This is in violation of the licenses both wiki operate under,
Also: There is one instance where a wiki was allowed to leave and completely wipe the (at the time, still Wikia if not WikiCities) original version from Jimmy Wales' server for good: WikiFur. I don't know how that happened, and I'm still kicking myself for never asking the owner about it when he was still around.
