Then Special:Contact/general is where you should be submitting a ticket. The user has already been blocked on the offending wiki, and it's up to those admins to revert the vandalism.

I have a feeling Rappy will tell you the same thing. Anytime staff should be informed about an issue, S:C is the place to go.
