As for doing it for any open proxy, if you know how to do it, please share it. I think it was proposed a long time ago to automatically scan for open proxys. Don't know it if was really done, but it's certainly impossible to do now.
You just do a portscan. It's fairly straightforward. (Also not *totally* reliable, but what is in life?) Wikimedia could then maintain its own DNSBL, if it were feeling nice. Each view would trigger a portscan on that IP, although no more than once every X days. Any hit would be added to a table of proxies that would be checked on edits, etc.
This exists in our codebase, but was turned off because very few ISPs, nor our network admin Mark, liked our software portscanning ~20% of the internet per day.
