If we're just talking about the look or formatting of the signature, I don't think there's an issue there: the vast majority of the wikis on Wikia are under various forms of Creative Commons licensing, so people don't have any legal right to stop someone else from copying elements of their signature (e.g. the colour, formatting, etc).

On the other hand, the Terms of Use forbid users from "attempting to another user or person", so if that's what they're copy-pasting the signatures for, then you might have an issue there.
