Deus ex Machina
A simple solution would be to access the free proxy list using your web browser, then copy/paste the IP and port addresses to create the plain text list. However this is very tedious, so we created a tool that does this job automatically for you.
Update 21-Nov-17: Sadly hidemyass website no longer offers free proxy lists so this tool is useless. If you want proxy lists by country try this website
After installation, run the tool and type in the country name, then click get proxy servers button. After a little while, you will see a list of IP:PORT addresses (operating in that country) in the results window — see the picture to the right. Note that country names must appear as in the proxy country box, e.g. United States for USA etc. Finally use copy results button to put them in the clipboard and from there paste in Web Proxy Checker for testing as explained before.
The proxy list table in hidemyass website is clearly designed to spoof automatic screen scrapers, but nothing will resist the crack tracker script engine <g>
