It's not going to get your admin rights removed and banned from the wikia for adding it to the MediaWiki:Wikia.css page. To avoid harassment here, I'm not forcing you to try it. You don't have to use them if the community doesn't mind having them shown on recent changes. It's up to you when you're the admin on a wikia.
