You can catch the vast majority of those with a scant few regexes tested 
against the URL:

(nph-proxy.[cgi|pl])
(nph-proxya.[cgi|pl])
(nph-proxyb.[cgi|pl])
(nph-surf.[cgi|pl])
(nph-one.[cgi|pl])
(nph-teste.[cgi|pl])

That'll work until the kids figure out to rename the path to their 
proxy.  Then you'll have to use deeper inspection.
