Well here is what I usually check...
 * MediaWiki:Common.css for direct *.wikia.com URLs
 * MediaWiki:Wikia.css for direct *.wikia.com URLs
 * MediaWiki:Common.js for direct *.wikia.com URLs
 * MediaWiki:Wikia.js for direct *.wikia.com URLs
 * Special:LinkSearch for direct *.wikia.com URLs (http:// and https://)

So far I haven't found anything that would obviously break, since most of the URLs have redirects, but I did find a few direct *.wikia.com URLs for images in CSS pages and links on a few pages. I've only check 2 or 3 wikis.
