Unfortunately, WebmasterWorld doesn't allow URLs to be posted for this sort of thing, so presumably the moderators will shortly be blanking these out. Not sure what this is - the URLs you posted don't lead to anything that makes much sense. The main URL you posted leads to an apparently static page that is a capture of a Google search for "cash", with the site's domain name substituted for "Google" everywhere - in the text, in links, etc. None of the links are functional, and the search box is not functional either. The static page shows a particular user logged-in.
The second URL you posted leads to a blank page. (Edit: it did the first time I tried it. Now it leads to a a web site for a car club. Presumably, this is your site?)
It looks like it might be a poorly-implemented attempt at a proxy server. I'm thinking that they aren't intending to be abusive - just to skirt the Great Firewall of China. But damage is damage, and they need to stop if it is hurting sites.
The site is registered to a person in China. The site is hosted in the U.S., though, so you are in luck.
I will sticky you the phone number of the host's abuse team in Texas. Good luck!
