This is a bit of a different situation, because the duplicate is off-Wikia. It looks like the duplicate is off-line now, which hopefully solves the problem. If it comes back, they may be able to use the content under the license - but they have to give attribution. If they don't do that, then you may be able to send a DMCA takedown notice and insist they remove the wiki that way.

But this isn't my area, so to get more advice (if the site returns) then use the contact form, and explain the situation fully. Then someone can look over the situation for you.
