I (and perhaps we all ) need a list of working proxy IPs time to time. So lets share all our tools and resources to get the lists of working proxies anytime. The best one I have found till yet is proxy-list.org Its checks the proxies after every two mins. The best part is that you can download the full list anytime. This site has really helped me to feed my tools with proxies. If you have any other tools/resources to contribute for the purpose, feel free to share here.
