EVERYTHING you put on Wikia is under the CC-BY-SA license (okay, with a few exceptions, but generally it is CC-BY-SA). Scroll to the bottom of this page: "Content is available under CC-BY-SA." And that link will tell you: "By editing or otherwise contributing to a wikia that uses the CC BY-SA license, you agree to license any text you change or contribute under the CC BY-SA license."

That means anyone can "re-distribute and re-use their contributions freely for any purpose, including commercial use."

That link also describes how this person must give attribution to the original source (your wiki):

When re-using Wikia text that has been posted subject a Creative Commons license, you must provide attribution to the authors using one of the attribution methods described...

Attribution example when re-using Wikia content on your own website:
 * This article uses material from the "Endor" article on the Star Wars wiki at Wikia and is licensed under the Creative Commons Attribution-Share Alike License.

So the most you can do is ask that this person add such attribution somewhere on every copied page, or you can go and add it yourself (it's a wiki; anyone can edit it!). Help:Copyright is mostly saying that you can't take copyrighted content from off-Wikia sites and copy it onto Wikia (and how one can get their copyrighted content removed from Wikia if someone has posted it, specifically by emailing ). So that's not very useful for what you're asking here.

Basically, every time you publish an edit on Wikia (or Wikipedia for that matter), you are allowing this sort of thing. This user has done nothing wrong in copying all of "your" content, because it is published under CC-BY-SA, which specifically allows doing exactly that. The only thing you can do is ask for the attribution to be added, or add it yourself.

If you do add attribution, and this user removes it, THEN you may wish to contact Wikia and let them know what's happening. They may be able to convince the person to stop copying content if they won't give attribution, convince the person to give attribution when copying content, or even shut down the wiki if they can't follow the content license and give attribution.
