I believe he was using this IP yesterday, which is from the multiproxy list of servers in Mexico:

customer-148-223-48-114.uninet.net.mx:80

[tmp02]

Do a search for anonymous proxies in google. You could get hundreds of pages with anonymous servers. multiproxy is not the only page with anon. proxies and does not produce an exhaustive list. Give it a try...
