If you ask the person to attribute the content and they refuse (i.e. they're violating the license) ... there's not much you can do.

In that case, you could file a complaint to Wikia staff at Special:Contact/general letting them know that someone is copying your content to another Wikia wiki and violating the CC-BY-SA license by refusing to attribute it to you after you asked them to attribute it.
