Tool that can scrape proxies, or you can import yours.
It can check proxies very well too.
I found this tool here, but full of viruses and i think i cleaned it. But just to be sure, use in rdp, i do not take any liability for anything
Im including 15 proxy APIs, which will get you around 45k unchecked proxies
