I think we need to fight fire with fire. I suspect that the scammer behind the .xyz site spammed google with "legal removal" requests, probably with a bunch of different google accounts.
I've just reported the .xyz site as malware using the link below. I suggest we all submit a report, making it hard for google to ignore.
