As for doing it for any open proxy, if you know

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.
