It's not in the public domain.

Also, even though most text in these wikis falls under the Creative Commons license, you could, in theory, copyright portions of it and cite that they are copyrighted and reproduced on the wiki with permission.

Just because the wiki is under a particular license doesn't mean all the text in it is governed by that license. For example, many wikis reproduce blurbs about TV shows or episodes on their wiki pages and those blurbs are often copyrighted. The rights holder could request it be taken down and anyone who copied that page before the takedown would be in violation of the copyright.
